 - PoW datatype now saves the calculation result to be used for checking proof validity given input
 - `is_valid_proof` method to do the above mentioned

+- `is_sufficient_difficulty` method to check difficulty with new changes
 
 Other small changes have also been included of various importance but mostly just stylistic/ease of use improvements.
