Performance improvements and bug fixes

Your repels might stop working when updating to this version. You can fix this by breaking and placing them back.

Changes

• Spawns check for repels using Minecraft's POI system, the same system used for Villagers and Bees.
• superRepelRangeMultiplier and maxRepelRangeMultiplier's minimum set to 1
• Repels no longer stop Pokémon spawned through fishing
