ExpandMsgXmd expands the msg with the domain to output a byte array with outLen in size using a fixed size hash.

ExpandMsgXof expands the msg with the domain to output a byte array with outLen in size using a xof hash See https://datatracker.ietf.org/doc/html/draft-irtf-cfrg-hash-to-curve-13#section-5.4.2.
