Use custom decoding instead of just jerasure_matrix_decode()
- Cache the decoding matrix
- Don't do unnecessary erasures->erased conversion during decoding
- Avoid extra memory allocations during decoding
- Don't always reconstruct coding chunks
- Reconstruct chunks one-by-one, without overlapping ranges
