[Jovonni]

Remove hardcoded public key, and pass into verify. Will change tests as well.

Also alter the function in the Verifier trait to accept base64 pub key as parameter:

Change from

Signature::verify(digital_signature, String::from(signature_result), content); 

to

Signature::verify(digital_signature, public_key_base64, String::from(signature_result), content);
