FAWE Arena regen, no per world arenas

[Arcticnotfound]

Hello, I have a suggestion to add corners and making arenas reset without switching copying deleting or creating any world. By this you can have infinite number of arenas in a world, prevent players from escaping the corners, it is much more performance friendly on newer versions too. Fast async worldedit can be used. Please think about this. Thank you!

Something like this is partly added; config option plugin.regenerate_worlds=false makes it so the arena caches displaced blocks so instead of creating/removing a world on every reset it just restores blocks from that cache. (Without FAWE dependency) Arena corners to prevent players from 'far' basing also exist, but they are not mandatory for arena setup.
On the other hand, the idea of multiple arenas in a single world sounds good, and since the suggestion has come in the right time, (I'm about to tweak a little how arenas load ands save after the inventory rewrite) I'll give this a look to see what I can do.
