Add option to only backup claimed chunks

[Lyfts]

I didn't feel like dealing with the merge conflicts so it's currently based on #100 and will be drafted for now,

This extracts only the chunks that are claimed and saves them to a temporary region file which then gets zipped up, the final result is much much smaller than your usual backup and created in a fraction of the time.

Here is two chunks about to be mercilessly blown up, the one on the left is claimed and the one on the right is not. Above them is a chest full of delicious melon.

This is after several OSHA violations occured and is also when the backup was taken.

And finally we have the chunks after the backup was restored. This shows that only the claimed chunk remained in it's previous state while the unclaimed one was regenerated from new. (two of the obisidian lines were outside the chunk border)

The melons survived too

Old test which showed a mysterious patch of mossy cobble regenerating in the claimed chunk

This line of tnt is directly on a chunk border between a claimed (on the left side of the tnt) and an unclaimed chunk

This is the result of the explosion

And this is after restoring from a backup, showing that only the claimed chunk on the left remained the same while the unclaimed regenerated from new. For unknown reasons Minecraft generated a patch of mossy cobble in the claimed chunk after restoring from backup, which will need to be investigated.

Closes #75

Just tested this on my old UMV world where it brought the backup size down from 3.2GB to just 34MB whilst keeping my entire base & all my many random claims intact and working.

It was small enough that it only took a staggering 5 seconds to upload it as proof if anyone wants to check it out

This should require a Void Miner controller to enable, otherwise it provides infinite resources 👏

[Caedis]

@S4mpsa if people are purposely restoring backups, they might as well give themself creative mode

[S4mpsa]

It was more of a joke, I don't think we can enforce config options with in-game progression 😅

@jusvit you need to update gtnhlib

Results for 6GB Server world with 19 teams (~25 players)

Log

[Server Utilities]: Backed up 103 regions containing 3408 claimed chunks
[Server Utilities]: Backup done in 00:19 seconds (94.5MB)!

Results

Not good, chunks are mix and matched, looks like the matrix.

Although the zip size is 98.471% decrease from a complete backup :)

This should be flat grass (personal dimension) but it seems to have sections of the nether, and the overworld.

This is the overworld but it has my personal dimension base there.

This is my personal dimension, it seems to have my moon base, a bit of my original overworld base, some nether chunks and my actual base at the back.

Not sure what's going on, I think the claims were copied to each dimensions and overlapped.
The original bases (in their actual location) all seem good and dandy.

I can provide you the world if you want, I sent you a friend request on discord, accept if you want the world.

Fixes look good, chunks are as-expected.

[Caedis]

Is this going to be default on?

[Lyfts]

Nah it will be disabled by default

@Lyfts i open this because #100 is now approved and merged .
