pre-hashed message in ECDSA and EdDSA

[yelhousni]

Following the signature interface, for both ECDSA and EdDSA:

// If hFunc is not provided, implementation may consider the message
// to be pre-hashed, else, will use hFunc to hash the message.

Looks good and I think is good to merge as-is. Your call if you want to merge currently as-is and have later optional PR if have figured out #322 or wait and incorporate changes.

I think we can merge now as-is since the two other PRs #313 and #314 are based on this branch. Then we can have a PR that refactor all of the 4 schemes (EdDSA, ECDSA, Schnorr, BLS) in a similar manner as per #322.

Makes sense and I agree.
