Add support for 1.21.3 + make all the 1.21.x versions a single file (the CyanLib doesn't use things that changed between the different 1.21 versions, so separating each version is not needed)
Add support for 1.21.2
Make compatible with both 1.21 and 1.21.1
Backport to 1.20.1
- Fix bugs with the config not detecting new options when the config file was present
