Reed-Solomon BCH encoder and decoder implemented in Rust.
This is a port of python implementation from Wikiversity
This is a fork of https://github.com/mersinvald/reed-solomon-rs - the primary change being that it operates in GF(2^5) instead of GF(2^8) and that the public API has been modified.
