Features
- Added advanced jukebox upgrade
- Has multiple slots that can hold music discs and plays them one by one
- Has controls to go skip between discs played
- Allows playing discs in random order by using Shuffle toggle
- Allows repeating all or the current disc played
- Mobs that spawn with jukebox in their backpack will now sometimes have an advanced one with possibly more than one disc in them
Fixes
- Fixed backpack data to properly save after backpack removal, also made it so that data of backpack worn by mobs is removed a bit more aggressively - in rare circumstances that would make jukebox upgrade disappear from these bags if the mob has just unloaded, but should fix the issue of backpack data continuously getting bigger the older the world gets
