Schnorr and ECDSA extended to non-string arguments

[codygunton]

By using auto I extended the native ECDSA and Schorr signatures code to take in not just strings, but byte arrays. Probably using auto here without any constraints is unwise. Someone should review (some of this code has been audited externally).

@ledwards2225 The code referenced by this issue is not part of bb. More precisely, the code referenced by this issue is this but in bb we have this.

In short: in bb we don't have auto message, we have std::string message.

Do you have any more info/do you think this issue should be closed?

Weird, I don't know what that is, some kind of unused fork. Looks like we can close
