daxpedda bebd2c605b SIGMA-I Key Exchange (#378) 
* Move `KeGroup` to `KeyExchange::Group`

- Introduce `KeyExchange::Hash`, which separates the OPRF hash from the one used in `KeyExchange`.
- Remove `De/Serialize` requirement on key exchange messages and states, which forced a lot of where bounds on downstream users.
- Rename `KeGroup` to `Group`.
- Replace `D` generic for hash with `H`.

* Use `voprf::derive_key()` directly

* Implement SIGMA-I key exchange

* Improve `KeyExchange` for SIGMA-I and Ed25519

* Implement EdDSA

* Un-qualify some method calls

* SIGMA-I: only include client identity in client mac

* SIGMA-I: include server mac in client signature

* Expose key exchange types in `crate` & move modules

* Implement Ed25519ph

* Document `ed25519` crate feature

* Remove `ristretto255-voprf` crate feature

* Adjust CI crate feature testing
