it is possible to use ooz in repack however, let me say why it's a BAD idea though,
even if:
1) make it work with stdio via patch or
2) make it work with chunks and cls
3) ooz is slower than lolz, and gives worse ratio too.
ooz is based on oodle, oodle is a gaming compression API therefore games release compressed with it already
Games like FIFA and Sekiro use it out of the box.
we have made a precompressor for it, xtool uses oodle and a separete tool called poodle.
why would someone want to use xtool + srep + ooz? I have seen people go as far as to use xtool + srep + zstd, zstd is even worse than ooz.
I will try to pop cls for it here if you want for benchmarks
