LZMA2 compression instead of DEFLATE

[seacat17]

I decompressed the replay file and performed a quick test. With the in-mod compression it results in 151mb. With hardest DEFLATE compression it results in 150mb, while taking whole 7 minutes to compress on my Ryzen 5 5600H.

But LZMA2? On second-to-fastest preset it results in 130mb while being able to compress the replay in just 4 seconds on the same CPU.

EDIT: With higher efficiency the same file results in just 29mb!
