Subject: [PATCH] Haskell-Generate: stop referring to `Midstate` explicitly

This is an unnecessary encapsulation violation (Haskell-Generate doesn't
need to know how Cmr is implemented when it just needs to construct one
from a byte array), and also it'll stop working when we move to
bitcoin_hashes 1.0.
