Bcml

Honestly, I've fixed so many little bits in this I can't do a useful changelog *except* to say that Switch mods can now drop `atmosphere/contents` and just use `TITLEID/romfs`.

This releases fixes a couple issues from the beta so far:
- The Update BCML feature should work, and is now the preferred way to update for both `pip` and the executable setup installs
- Fixed enabling and disabling mods
- RSTB estimates for AAMP files on Switch should be more reliable
- Minor fix to dependencies and the `bcml-debug` command
- RSTB merging may perform better
- Fixed some minor UI bugs like dialogs with nonfunctional close buttons

Correct some initial bugs, particularly with saving files, and also adds completely separate folder settings for Wii U and Switch

Too many changes to document for just the beta; I'll do a real writeup for the proper release. In the meantime, try it out and check Discord for my help.

This release makes significant improvements to the RSTB estimation feature for AAMP and BFRES files. Because it is now at least 99.99% reliable, it is enabled by default.

Fixes the last of the float/int-related RSTB bugs
