Add support for 1.21.2 + change how BackTps and Locations are handled internally
Add the /cyan execute <command> <player_targets> <eventual_command_arguments>.
This command allows the OP users and the console of the server to execute a given command for the player_targets (can
be player names or a selector like @a)
The possible commands that go with it are :
/bed/surface/location <location_name>
Backport to 1.20.1
Allow the user to choose whether XP points or XP levels will be used when teleporting
