`sloth256-189`

Encoder/decoder for the Subspace Network Blockchain based on the SLOTH permutation

This is an adaptation of SLOTH (slow-timed hash function) into a time-asymmetric permutation using a standard CBC block cipher.

Implementation contains 3 flavors: * optimized assembly-assisted implementation for x86-64 processors with ADX ISA extension (Linux, macOS and Windows) * any 64-bt platform with support for __int128 C type (modern GCC/Clang, but not MSVC) * fallback for other platforms
