Add bindings for `ahash`

[uselessgoddess]

ahash is a non-crypto crazy fast hash algo without SSE and AVX instructions only for hash maps.

[Konard]

Can we make a benchmark? Does it provide good distribution of data?

I don’t see compassion with crc32 in this paper.

Lol. Crc is insecure, 100% bias, collisions, distrib, BIC, machine-specific (x86 SSE4.2+PCLMUL) But I make simple tests At random data:
