CatLib 2.0 (1.18.2)

This version includes a port to Minecraft 1.18.2, a handful of fixes, and replaces Hjson with XJS, a new JSON superset designed to be far easier to use in the context of Minecraft mods.

Note that most of the previously deprecated code has been removed in this version.

• New package structure. Most references will need to be reimported.
• Most of the old Hjson code has been replaced, but only the packages have changed, with a few exceptions.
• The upgrade to XJS has replaced most of HjsonUtils, now known as XjsUtils.
• Renamed JsonTransformer#recursive to #scan, which is more accurate.
• All deprecated methods and classes have been removed.
• Temporarily removed support for custom structures in FeatureModificationContext. This will have to be moved to a new utility for 1.18+.
• Most other code is largely unchanged.
