[maintain] [Publish]

An algebraic hash function, inspired by the paper "Hashing with SL2" by Tillich and Zemor.

The hash function is based on matrix multiplication in the special linear group of degree 2, over a Galois field of order 2^127, with all computations modulo the polynomial x^127 + x^63 + 1.

This construction gives some nice properties, which traditional "bit-scambling" hash functions don't possess, including it being composable. It holds:

hash (m1 <> m2) == hash m1 <> hash m2

All operations in this package are implemented in a very efficient manner using SSE instructions.
