* Initial mod loader implementation.
* Allow iterating in mod directories.
* Initial append archive implementation.
* Avoid calling function wrappers when loading append ARs.
For some reason they cause issues. Should investigate later.
* UMM merge archive support.
* Load merge archives without archive lists.
* Less thread locals.
I shouldn't worry about string allocations this much when the game itself spams them...
* Check for read-only UMM archives.
TODO: Skip merging as it's currently just doing duplicate loads.
* Skip loading merge archives if they are read-only.
* Merge only archives.
* Implement decompression.
* Fix append ARLs not loading.
* Initial save file redirection implementation.
* Slightly refactor resolved path usage.
* Implement save file redirection fallback.
* Set a default save file path if none is provided.
* Check for enabled option & replace backward slashes with forward ones in mod save file paths.
* Convert back slashes to forward ones when iterating directories.
* Make CSB limit dynamic.
* Cache append/merge archive lookups.
* Close stream after reading compressed ARL.
* Fix UMM/HMM ARL file path inconsistency.
