The Backrooms Dimension!

This datapack adds an Infinite Backrooms dimension to your save file. (Backup your world first!)

Currently, you can enter the backrooms, by jumping into the void, either in The End, or by breaking through bedrock (somehow)..
There's a rare possibility that you may spawn inside a closed off area, in which case you'll have to try breaking through walls, spectate, or try a different spot. Shouldn't be an issue tho, virtually all areas have at least one connection to other areas.

Alternatively, you can enter/exit with commands:
To enter The Backrooms:
/tag @p add EnterBR
Or the old way:
/execute in nik_br:backrooms run tp ~ 20 ~
To exit:
/execute in minecraft:overworld run tp ~ 100 ~
(Or change "~ 100 ~" to whatever you know are safe coordinates.)

Please note, this is a Work In Progress, and only works in 1.19+, since it uses the new features in datapack format 10.
This pack also currently requires commandblocks be enabled, for the exits to function. (Tho I'll try to change that soon.)

Future ideas:
- More interesting things to find/loot, or maybe puzzles or traps?
- Better custom/altered mobs, or better way to spawn them..
- Deeper levels of The Backrooms, maybe more structure variations..
- Possibly a different method to enter/exit.
(I'm open to suggestions/design ideas for all of those.)

Possible issues:
- While this datapack seems to work fine for normally generated single-player maps, so far I can't seem to get it working on my server's flatmap. If anyone knows a solution, I'd really appreciate it!
