💡 Considering nncp as a new backend

[pete4abw]

nncp, a neural network compression program by Fabrice Bellard ranks tops in the Large Text Compression Benchmark. While painfully slow, it is another backend to consider. Running lrzip-next -L9 -n file and then running nncp c file.lrz file.lrz.nncp yields around a 1.5-2% benefit over running nncp alone.
See Bellard.org for more info.

The challenge will be that nncp is meant to be used only for files. So a memory interface will need to be developed. In addition, the compression library provided is binary only and only for x86. This may limit the possibility.

More as this progresses.
