Per bitcoin/bips@200f9b2 there is no longer a requirement to check message length when signing or verifying BIP-0340 Schnorr signatures. This commit updates the signing and verification algorithm and adds test vectors from the BIP for arbitrary-length messages. It also adds a test to ensure we avoid RFC6979 nonce collisions when signing messages that aren't 32 bytes long.
