[PATCH v4 0/5] MR9061: cabinet: Add LZX compression support to FCI

[Eric Lasota (＠ejlasota)]

This adds LZX compression support to FCI.

Most of the work for this was done here: https://github.com/elasota/liblzx

The LZX compression code is based on the LZX compression code from wimlib with modifications to support the cabinet variant and streaming compression.  Eric Biggers (the author of wimlib) has given permission to redistribute the modified LZX code under LGPLv2 terms: https://wimlib.net/forums/viewtopic.php?t=854

I've been testing this against some large data sets (dumped game assets, Visual Studio installation) with a test program and decompressing with 7-zip and diffs have been coming back OK.
