OpenBagTwo's Custom Items

Turns out, quite a lot.

Due to changes in pack formats, several of the existing packs will no longer function on 1.20.4. Additionally, that update entirely broke the datapack "printing" functionality thanks to how custom names are stored in block and item NBT.

See: https://bugs.mojang.com/browse/MC-267451

In addition to adding 1.20.4 support, this release:

• restores 3D printing and brewing functionality to the datapack (both old and new blocks and "gcode" paper will work).
• allows you to generate Totems of Iskall using paper named iskall.gcode
• results in an ender pearl being called an "Ender Pearl" when using both the Moonescent Pearl and "Chappeau" datapack, so long as "Chappeau" is higher in priority
• Accounts for the name change of the "grass" block (not to be confused with the "grass block" block) to "short grass"
