Add hazmat module with ExpandedSecretKey, raw_sign, raw_sign_prehashed (#299 )

* Added raw_sign() and raw_sign_prehashed() functions

* Renamed `nonce` to `hash_prefix` in signing because it's really not a nonce

* Moved raw signing to hazmat module

* impl From<EdwardsPoint> for VerifyingKey

* Brought back ExpandedSecretKey; made raw_* functions take it as input

* Added remaining features to docs.rs feature set

* Removed redundant ExpandedSecretKey def; made raw signing use a generic CtxDigest

* Implemented raw_verify with generic CtxDigest

* Implemented raw_verify_prehashed with generic MsgDigest and CtxDigest

* Wrote hazmat tests; fixed errors; switched ordering of MsgDigest and CtxDigest

* Updated changelog

* ExpandedSecretKey::from_bytes takes an array and is now infallible

* Add TODO comment for split_array_ref

* Added from_slice and TryFrom<&[u8]> for ExpandedSecretKey
