Update the license to VNPL 1.1
...
VNPL 1.1 is slightly reworded to make it clear that proprietary software
interacting with Vitastor and providing some kind of service to end users isn't
a "Proxy Program" if it's not specially designed to be used with Vitastor.
For example, Windows OS running in a virtual machine stored in a Vitastor
cluster clearly isn't.

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
