-Subject: [PATCH] PreCreatureSpawnEvent
-1.17: Has to be looked into more
-Adds an event to fire before an Entity is created, so that plugins that need to cancel
-CreatureSpawnEvent can do so from this event instead.
-
-Cancelling CreatureSpawnEvent rapidly causes a lot of garbage collection and CPU waste
-as it's done after the Entity object has been fully created.
-
-Mob Limiting plugins and blanket "ban this type of monster" plugins should use this event
-instead and save a lot of server resources.

-See: https://github.com/PaperMC/Paper/issues/917
