Update the sign, verify, proofgen and proofverify procedures to the latest specification #28

Closed tplooker closed 2 years ago

Since this implementation was originally built, the specification behind BBS signatures has significantly change. See here for more context. We can elect to address the changes required across the different procedures in seperate PR's to facilitate easier review if required, it will just break the existing test cases until all are migrated.

Major task split:

reimplement generators
updatation of sign/verify/proof_gen/proof_verify procedures
serialization of different artefacts (use of I2OSP, OS2IP)
implement MapMessageToScalarAsHash and HashToScalar utilities
adding of ciphersuites
testing - unit, and integration

First two tasks are complete via #32
