Refactor AVX512 code to use Go assembly instructions. (#121) 
Additionally there is a small performance improvement using VPTERNLOGD (instead of two VPXORD instructions).

Frank Wessels 79aee05119 AVX512 accelerated version resulting in a 4x speed improvement over AVX2 (#91) 
The performance on AVX512 has been accelerated for Intel CPUs. This gives speedups on a per-core basis of up to 4x compared to AVX2 as can be seen in the following table:

```
