[feedback] memory usage and lznt1 support

[SeriousConcept1134]

I've tried CompactGUI for the first time today, and I really like almost everything about it except a couple of things:

• Why is it taking up anywhere from 300-500MB in RAM when it's just idling in the background? For comparison, something like CompactRS takes just ~21MB while actively performing compression operations.
• It would be great if CompactGUI supported evaluating and directly recompressing directories which are already compressed with LZNT1, rather than just throwing an error saying they're unsupported and refusing to even open them. This is a big limitation.

Thanks!
