Added backends for the BLAKE2 family of hashes.

Browse source 
There are a lot of different variants and sizes, I suppose we might as well
export all the common ones.

Bump dep to cryptonite to 0.16, earlier versions lacked BLAKE2 support.
Even android has 0.16 or newer.

On Debian, Blake2bp_512 is buggy, so I have omitted it for now.
