fix: install ca certs

rageshake stores logs and screenshot in the same directory as the binary.
Copying binary to /bin/ will, well, mess /bin/ up. Not good.

+## Generic webhook request
+
+If the configuration option `generic_webhook_urls` is set, then an asynchronous request to

+files are uploaded.
+
+The webhook is designed for notification or other tracking services, and does not contain
+the original log files uploaded.
+
+(If you want the original log files, we suggest to implement the rageshake interface itself).
+
+A sample JSON body is as follows:
+
+```

+  'app': 'element-web',
+  'data': {

+# Common report styles
+
+Rageshakes can come from a number of applications, and we provide some practical notes on the generated format.
+
+At present these should not be considered absolute nor a structure to follow; but an attempt to document the currently visible formats as of January 2022.
+
+## Feedback 
+
+Log files are not transmitted; the main feedback is entirely within the user message body.
+
+This occurs from all platforms.
+
+## Element Web / Element Desktop
+
+Log files are transmitted in reverse order (0000 is the youngest) 
+
+Log line format:
+```
+2022-01-17T14:57:20.806Z I Using WebAssembly Olm
+< ---- TIMESTAMP ------> L <-- Message ----
+
+L = log level, (W=Warn, I=Info, etc)
+```
+
+New log files are started each restart of the app, but some log files may not contain all data from the start of the session.
+
+## Element iOS
+
+Crash Log is special and is sent only once (and deleted on the device afterwards)
+
+`crash.log`
+
+Following logs are available, going back in time with ascending number.
+console.log with no number is the current log file.
+```
+console.log (newest)
+console-1.log 
+...
+console-49.log (oldest)
+
+console-nse.log (newest)
+console-nse-1.log 
+...
+console-nse-49.log (oldest)
+
+console-share.log (newest)
+console-share-1.log
+console-share-49.log (oldest)
+```
+
+## Element Android
+
+There is a historical issue with the naming of files, documented in [issue #40](https://github.com/matrix-org/rageshake/issues/40).
+
+Log file 0000 is odd, it contains the logcat data if sent.
+
+Log line format:
+```
+01-17 14:59:30.657 14303 14303 W Activity: Slow Operation: 
+<-- TIMESTAMP ---> <-P-> <-T-> L <-- Message --
+
+L = Log Level (W=Warn, I=Info etc)
+P = Process ID
+T = Thread ID
+```
+Remaining log files are transmitted according to their position in the round-robin logging to file - there will be (up to) 7 files written to in a continious loop; one of the seven will be the oldest, the rest will be in order.
+
+Log line format:
+```
+2022-01-17T13:06:36*838GMT+00:00Z 12226 D/ /Tag: Migration: Importing legacy session
+< ---- TIMESTAMP ---------------> <-P-> L        <-- Message ----
+
+L = log level, (W=Warn, I=Info, etc)
+P = Process ID
+```
+
+Once the fix to #40 is in place, we will see the following files:
+
+```
+logcatError.log
+logcat.log
+crash.log
+keyrequests.log
+log-[1-7].log
+```
+
+Log 1-7 are logs from a round-robin buffer and are ordered but the start point is undefined

-// Package fields provides a view of the fields of a struct that follows the Go
-// rules, amended to consider tags and case insensitivity.
-//
-// Usage
-//
-// First define a function that interprets tags:
-//
-//   func parseTag(st reflect.StructTag) (name string, keep bool, other interface{}, err error) { ... }
-//
-// The function's return values describe whether to ignore the field
-// completely or provide an alternate name, as well as other data from the
-// parse that is stored to avoid re-parsing.
-//
-// Then define a function to validate the type:
-//
-//   func validate(t reflect.Type) error { ... }
-//
-// Then, if necessary, define a function to specify leaf types - types
-// which should be considered one field and not be recursed into:
-//
-//   func isLeafType(t reflect.Type) bool { ... }
-//
-// eg:
-//
-//   func isLeafType(t reflect.Type) bool {
-//      return t == reflect.TypeOf(time.Time{})
-//   }
-//
-// Next, construct a Cache, passing your functions. As its name suggests, a
-// Cache remembers validation and field information for a type, so subsequent
-// calls with the same type are very fast.
-//
-//    cache := fields.NewCache(parseTag, validate, isLeafType)
-//
-// To get the fields of a struct type as determined by the above rules, call
-// the Fields method:
-//
-//    fields, err := cache.Fields(reflect.TypeOf(MyStruct{}))
-//
-// The return value can be treated as a slice of Fields.
-//
-// Given a string, such as a key or column name obtained during unmarshalling,
-// call Match on the list of fields to find a field whose name is the best
-// match:
-//
-//   field := fields.Match(name)
-//
-// Match looks for an exact match first, then falls back to a case-insensitive
-// comparison.

-Equal returns true iff protocol buffers a and b are equal.

-  - Two messages are equal iff they are the same type,
-    corresponding fields are equal, unknown field sets
-    are equal, and extensions sets are equal.
-  - Two set scalar fields are equal iff their values are equal.
-    If the fields are of a floating-point type, remember that
-    NaN != x for all x, including NaN. If the message is defined
-    in a proto3 .proto file, fields are not "set"; specifically,
-    zero length proto3 "bytes" fields are equal (nil == {}).
-  - Two repeated fields are equal iff their lengths are the same,
-    and their corresponding elements are equal. Note a "bytes" field,
-    although represented by []byte, is not a repeated field and the
-    rule for the scalar fields described above applies.
-  - Two unset fields are equal.
-  - Two unknown field sets are equal if their current
-    encoded state is equal.
-  - Two extension sets are equal iff they have corresponding
-    elements that are pairwise equal.
-  - Two map fields are equal iff their lengths are the same,
-    and they contain the same set of elements. Zero-length map

-Package proto converts data structures to and from the wire format of
-protocol buffers.  It works in concert with the Go source code generated
-for .proto files by the protocol compiler.
-
-A summary of the properties of the protocol buffer interface
-for a protocol buffer variable v:
-
-  - Names are turned from camel_case to CamelCase for export.
-  - There are no methods on v to set fields; just treat
-	them as structure fields.
-  - There are getters that return a field's value if set,
-	and return the field's default value if unset.
-	The getters work even if the receiver is a nil message.
-  - The zero value for a struct is its correct initialization state.
-	All desired fields must be set before marshaling.
-  - A Reset() method will restore a protobuf struct to its zero state.
-  - Non-repeated fields are pointers to the values; nil means unset.
-	That is, optional or required field int32 f becomes F *int32.
-  - Repeated fields are slices.
-  - Helper functions are available to aid the setting of fields.
-	msg.Foo = proto.String("hello") // set field
-  - Constants are defined to hold the default values of all fields that
-	have them.  They have the form Default_StructName_FieldName.
-	Because the getter methods handle defaulted values,
-	direct use of these constants should be rare.
-  - Enums are given type names and maps from names to values.
-	Enum values are prefixed by the enclosing message's name, or by the
-	enum's type name if it is a top-level enum. Enum types have a String
-	method, and a Enum method to assist in message construction.
-  - Nested messages, groups and enums have type names prefixed with the name of
-	the surrounding message type.
-  - Extensions are given descriptor names that start with E_,
-	followed by an underscore-delimited list of the nested messages
-	that contain it (if any) followed by the CamelCased name of the
-	extension field itself.  HasExtension, ClearExtension, GetExtension
-	and SetExtension are functions for manipulating extensions.
-  - Oneof field sets are given a single field in their message,
-	with distinguished wrapper types for each possible field value.
-  - Marshal and Unmarshal are functions to encode and decode the wire format.
-
-When the .proto file specifies `syntax="proto3"`, there are some differences:
-
-  - Non-repeated fields of non-message type are values instead of pointers.
-  - Getters are only generated for message and oneof fields.
-  - Enum types do not get an Enum method.
-
-The simplest way to describe this is to see an example.
-Given file test.proto, containing
-
-	package example;
-
-	enum FOO { X = 17; }
-
-	message Test {
-	  required string label = 1;
-	  optional int32 type = 2 [default=77];
-	  repeated int64 reps = 3;
-	  optional group OptionalGroup = 4 {
-	    required string RequiredField = 5;
-	  }
-	  oneof union {
-	    int32 number = 6;
-	    string name = 7;
-	  }
-	}
