Refactor k12

The k12 crate had its own keccak-p permutation implementation. With https://github.com/RustCrypto/sponges/pull/7 a generic keccak-p implementation would be available, which could be used within the k12 crate. Depends on - [...

There are a number of issues and comments floating around about this, so I thought I'd make a single tracking issue for this. Right now we have a separate [asm-hashes](https://github.com/RustCrypto/asm-hashes/)...

Currently we only have software and SHA-NI backends for SHA-256.

`blake2` code size very high (overuse of`#[inline(always)]`?)

I have ~150kb of code for `blake2::blake2b::VarBlake2b::compress` under `-Copt-level=z`, which is around 3x larger than any other function in my binary. It would be nice if it were smaller. Looking...
