  1. EdDSA with Schnorr (BIP340), supporting Taproot. In round 3, if R has… 

    … an odd Y coordinate, add aG to it so as to ensure R with even Y coordinate. Even though BIP 340 states that only R.X is used, the R recalculation in btcd/btcec/v2 's Signature.schnorrVerify checks if R = s*G - e*P. Without adding aG to R, it could have an odd Y coordinate and fail verification. This commit also fixed a previous serialization problem with s.
