The plugin should now work in the most recent versions (1.21.5 to 1.21.7)

- Fixed chest not despawning when modifying some properties
- Fixed setprotection command
1.21.7 compatibility, added option minimum spawn height, added option to prevent spawn on non-solid blocks
Fixed falleffect 1.21.5 class name, tested the plugin in 1.25.1 with success
Now checking if the player is in the same world of a chest before calculating the distance between chest and player

- Added minimum height for chests to spawn, so that void worlds like skyblocks can have them at a normal height (default height: -60)
- Added an option to prevent spawn on non-solid blocks (carpets, grass...)
- Added despawn command? idk if I added it before or if it's from this version lol
