Refactor azalea-protocol (#190)

* start updating to 1.21.4

* fix block codegen and stop using block data from burger

* rename packet related modules and structs to be simpler

* ItemSlot -> ItemStack for more consistency with mojmap

* .get() -> .into_packet()

* simplify declare_state_packets by removing packet ids

* rename read_from and write_into to azalea_read and azalea_write

* rename McBufReadable and McBufWritable to AzaleaRead and AzaleaWrite

* McBuf -> AzBuf

* remove most uses of into_variant

* update codegen and use resourcelocation names for packets

* implement #[limit(i)] attribute for AzBuf derive macro

* fixes for 1.21.4

* fix examples

* update some physics code and fix ChatType

* remove unused imports in codegen

* re-add some things to migrate.py and update +mc version numbers automatically

* downgrade to 1.21.3 lol
