Significantly speed up creating backups with isal via zlib-fast

isal is a drop in replacement for zlib with the
cavet that the compression level mappings are different.
zlib-fast is a tiny piece of middleware to convert
the standard zlib compression levels to isal compression
levels to allow for drop-in replacement

https://github.com/bdraco/zlib-fast/releases/tag/v0.1.0
https://github.com/pycompression/python-isal

Compression for backups is ~5x faster than the baseline
