Migrate to blake2b_simd and blake2s_simd crates 
The primary reason for migrating is that these crates provide APIs for
setting the personalisation string. This enables us to depend solely on
published crates, and thus publish our own crates.

The SIMD implementations are ported from libsodium.

Closes #67.

Return edwards::Point from sapling_ka_agree 
This matches how sapling_ka_agree and kdf_sapling are defined in the
protocol spec. kdf_sapling also now takes ownership of dhsecret to
discourage use of the sapling_ka_agree output elsewhere.

Switch to crypto_api_chachapoly crate 
This crate exposes both the ChaCha20Poly1305 IETF construction, and the
underlying ChaCha20 IETF primitive, removing the need for depending on
our own fork of the previous chacha20-poly1305-aead crate.
