Add ARM NEON versions of blake2s and blake2b NOTE! The NEON version of blake2s is currently NO FASTER than the reference implementations. However, it is retained for reference and in case it can be further improved. The NEON version of blake2b is more than twice as fast as the reference implementation on the Raspberry PI 2 Model B.
