This is a native python3 implementation of the FastLZ algorithm (more info in Lempel-Ziv 77 algorithm).
Currently it only implements decompression.
import fastlz_native
comp_data = bytes(raw_data)
decompressed = fastlz_native.fastlz_decompress(comp_data)
This implementation expects the decompressed size in bytes in the first uint32_t chunk.
