On Bedrock, a banner must be placed in the chestplate slot in order to be visible. On Java Edition, banners are placed in the helmet slot. This commit fixes the issue by migrating banners to the chestplate spot if the chestplate spot is empty.
This commit also fixes pillager poses if they're not holding a crossbow, along with a couple other optimizations.
- Merged ItemTranslator and ItemStackTranslator together.
- Split ItemTranslator into two classes: ItemTranslator and ItemRegistry. The registry is where items are registered, and the translator class is where item translation takes place.
- Made most of ItemTranslator's methods static and removed the initialization in Toolbox.
- Moved a handful of registry classes previously ending with 'Utils' to a 'Registry' class to be more fitting for the term.
- Moved inventory and block entity registration out of Translators.
- Renamed Translators to PacketTranslatorRegistry.
- Yeeted Toolbox.
- Minor cleanups and small refactors.
This should make the process of translating entity metadata a whole lot easier and more organized. Future features involving entities and checking if they're capable of doing certain things should also be much easier now.
