Fix a crash with other mods that bind 13+ textures simultaneously.
- MoreMcmeta now only updates actively-used sprites rather than all sprites on every tick. This should help performance with sprite-heavy resource packs on some computers.
- Fixes an issue where animation frame sizes that aren't multiples of the texture size would cause crashes.
- Metadata and texture error log statements have been lowered from ERROR to WARN.
