François Garillot 786bc51fdd Normalize generic parameters for LoginSecondMessage 
(aka use the CipherSuite just like the others)

Repair the generics in KE trait: it makes sense that generate_ke[1-3] should operate on the same key representation.

François GarillotandKevinLewi 9d40aa7659 As a way to roll back the genericity, implement an extension trait of group for password-to-curve hashing, 
This supersedes #18.

François Garillot 41cd80ccb5 Make oprf::generate_oprf1 generic in the Digest, as long as it matches the hash-to-curve intake of the group 
We used to have three problems:
- overuse of the <Sha256 as Digest>::OutputSize, which is just, well, U32. Sometimes used as a parameter (as in generate_oprf1), sometimes as a constant (as in generate_oprf3).
- the `hash_to_curve` operation for `RistrettoPoint` which requires 64 bits of input entropy, is fed 64 bits of which the last 32 are zero,
- the `hash_to_curve` operation for `Curve25519Point` which requires 32 bits of input entropy, is fed 64 bits of which the last 32 are discarded,

This corrects all three and uses U32 where the size of the digest is not meant to be a constraint.

Addresses #15 partially.

François Garillot c9d467e368 Add (normal) macros showing how to generate SizedBytes to/from TryFrom + to_bytes 
This is useful for getting serialization of the KEXState, KEXMessage formats without too much boilerplate

Add client_login, login_first_message roundtrip serialization tests
