Split World (Fabric)

Gameplay Changes:

* In the buffer zone, players will be set to spectator mode to prevent any and all actions that might allow them to try to get items across to the other side.

* spectator mode in the buffer zone will not allow you to pass through walls or ground by forcing players to stay above the highest available block at their coordinates.

* To prevent crossing into the survival zone and falling to your death, players will be teleported to the ground when they cross on the survival side

* buffer zone block replacement will go all the way down to bedrock to prevent issues with digging into the buffer zone and possibly getting stuck.

Config Changes:

* config files now use YAML instead of JSON which is much more readable
* config now can have separate options per dimension. Tested with the vanilla dimensions but theoretically you should be able to provide a mod dimension name and have it work

* config has a game mode override ('survival', 'creative', 'adventure', 'spectator') and enabled (true/false) options. when enabled is set to false it will fully disable the mod in that dimension except for game mode overrides. * Game mode override will forcefully set a player to the correct game mode and restore the respective inventory when they cross into that dimension
