[Feature]: support use slime world manager's load-template

[8MiYile]

Feature description

Ability to infinitely load multiple identical arena maps within one server
While map editing can only be done on the original map

Is your feature request related to a problem?

Yes, I hope this plugin can create and automatically unload multiple arenas based on an arena template configuration and work with Slime World Manager. This is very beneficial in situations with many players, as it allows multiple servers to be started without being based on the same arena
