Support form ARM Neon

[AudriusButkevicius]

First of all, this is great, thank you very much for producing this.

Secondly, could ARM platforms benefit from an implementation which uses Neon?

ARM would work by using Native Go implementation won't have any SIMD benefits yet.

Yeah, but Neon would bring it in par with performance of other platforms, and potentially beat whatever other hashes are available in the stdlib.

Anyways, this has the right tags, so now lets hope for a wild neon enthusiast to appear :)

Looks like Raspberry Pi 3 has NEON support :)

Here are some pointers for NEON stuff:

• BLAKE2_NEON_Compress32
• BLAKE2_NEON_Compress64
• Rust implementation of BLAKE2 with SIMD optimizations
