New Mob System

Not many extensive options for adjusting mob spawning.

Describe the solution you'd like
A new feature for mob spawning. Currently, there is a function to spawn mobs once when placing a sign.

My idea would be that you can use signs to define different points and then later set in the config which mobs should spawn, how often, and how many. When a player gets close again, they would respawn, similar to a regular Minecraft spawner, but without an actual spawner. This could prevent AFK farming for players, as there would otherwise be many spawners, which are difficult to control.
