Ask HN: Is There a Compression Primitives Library?

Would like a repo/library with code to calculate the Entropy, Bit I/O, Dictionary/Trie based list compression implementations. Maybe transforms like BWT, DCT, DWT. Maybe simplified implementations of Zstd, ANS. Is there a comprehensive one available with primitives/utils for these? Also see: https://medium.com/@duhroach/understanding-compression-69c874de6ad7
