Add support for Folia, dropped compability non PaperMC servers

For save compability this PR can be merged for special branch, if you created

[Mark-225]

I'll think about if/how I want to support Foilia in this project. Mainly, I want this to be able to run on as many versions BlueMap and the other plugins run on as possible. And that does include Spigot.
Maybe keeping this as a fork is the best approach for now but I might merge it into a separate branch in the future.

In any case thanks for creating this fork, more compatibility is always appreciated! :D

@KosyakMakc Your fork works with Folia, well done!
Only there is one issue, when a region with grief prevention is made, a java.lang.UnsupportedOperationException: null error is generated and the region is not shown on the bluemap. Only after a server restart the region is actually visible.

Grief prevention fork which is used on folia: https://github.com/ssquadteam/GriefPrevention-Folia

Would be nice to see folia support being added to the origin plugin soon :)

@sidboy55555 can you provide full stack trace of error?

@KosyakMakc
The fork seems to work fine with Folia 1.21.5, but if you create or modify a claim, an error is displayed in the console (see Pastebin). The change is only visible after a server restart.
