Crate reed_solomon_erasure

This crate provides an encoder/decoder for Reed-Solomon erasure code.

Please note that erasure coding means errors are not directly detected or corrected, but missing data pieces(shards) can be reconstructed given that the configuration provides high enough redundancy.

You will have to implement error detection separately(e.g. via checksums) and simply leave out the corrupted shards when attempting to reconstruct the missing data.
