FastNoise SIMD

Bindings for FastNoiseSIMD used by the safe wrapper fastnoise-simd-bindings.

FastNoise SIMD is the SIMD implementation of my noise library FastNoise. It aims to provide faster performance through the use of intrinsic(SIMD) CPU functions. Vectorization of the code allows noise functions to process data in sets of 4/8/16 increasing performance by 700% in some cases (Simplex).

After releasing FastNoise I got in contact with the author of FastNoise SIMD (naming is coincidence) and was inspired to work with SIMD functions myself. Through his code and discussions with him I created my implementation with even more optimization thanks to the removal of lookup tables.

Runtime detection of highest supported instruction set ensures the fastest possible performance with only 1 compile needed. If no support is found it will fallback to standard types (float/int).
