Change how EnderIO Zoo mobs spawn

Version
1.5.6

Describe the suggestion
Currently, a lot of mobspawns in certain dimensions like aether and glacidus get replaced by EnderIO Zoo mobs, to the point where especially in Glacidus it's very hard to find any naturally spawning mobs, which massively takes away from the appeal of those dimensions. This should be changed so that EnderIO Zoo mobs initially do not spawn when entering these dimensions.
The initial suggestion was for them to not spawn at all until later in progression, but seeing how you will not need to visit a lot of dimensions again either ever or until endgame the current suggestion is to slowly start spawning them after some time has passed, increasing their spawnrate as time goes on.

Additional context
From the private chat: "(...)Other than the overworld which I may just yeet them from"
The frequency of EnderIO Zoo mob spawns feels ok in the overworld in my opinion, and they should definitely stay as is in the hunting dimension since that even fits with the lore.

Alternative: Just yeet EnderIO Zoo

This affects a bunch of the dimensions especially in chapters 1 and 2:

• Atum
• Glacidus
• The Aurorian
• Dream Dimension
• Everbright
• Everdawn
• Misty World
• The Midnight
• The Aether
• Candora
• Altum

I did by far not go through all dimensions after chapter 2, but most seem to be unaffected other than some breathable Zollern dimensions, and while they did spawn in a few dimensions I did not list, they only spawned at ignorable rates
