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.

This library consists of 2 major implementations:

• CPU
• CUDA

---

CPU 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

For more details, README.md under src/cpu can be referred.

---

CUDA implementation is heavily using low-level PTX code to achieve the maximum performance.

Details of the CUDA implementation can be found in README.md under src/cuda.
