scrypt spends most of the time in salsa20_8 function, which can be significantly accelerated using explicit SIMD.

Per #29, an interesting way to do this would be to add SIMD support to the salsa20 crate, then use its implementation of Salsa20/8.

scrypt: use salsa20 crate to implement Salsa20/8

Closes #29.

Using the `salsa20` crate allows us to focus on a single place for
things like SIMD optimizations (#16).

As of #60, which switches to using the salsa20 crate, we can now track SIMD optimizations here: RustCrypto/stream-ciphers#50
