Fixed error when loading in 1.16

Fixed a bug making the result always 0.
Added a chunk mode, so the radius is counted in chunk and not in blocks.

Added multithreading. It creates a new thread for every Y layer. Hence, the calculation time is drastically lower.

For 1.17+ (only tested in 1.20), the items can be used to detect containers from y = -64 to y = 319.
Removed duplication glitch happening when the item is in off-hand.

Hey, it has been a while since last update.
I updated the plugin to 1.20, however I can't guarantee that it works for previous versions. Please let me know if it does work in versions you tried it on.

Added a NBT tag to make uses of custom resources packs possible
A ZIP example has been added to the description of the plugin

- I totally forgotten to update and recode the command, so now it's done
- /uf [item] to do the same as an unclaim finder (default item in config)
- /uf give [player=you] [item] to give a player an unclaim finder

- Fully recoded and optimized code
- You can now create your own item!
- You just have to duplicate the original file in the 'items' folder and replace the values
- the file name will be the id of the item
- You can edit lore whenever you want without breaking items
- Put '--' before file name to disable it
- Olds items won't work anymore
- Old versions (1.8 - 1.12) no longer working
