[Suggestion] Add ability to specify zombies from other mods in config.

[offbeat-stuff]

I am currently thinking something like

[Spawn.kind]
ids = ["minecraft:zombie","minecraft:husk","minecraft:zombie_villager","minecraft:drowned"]
weights = [100]
extraWeights = 30
conditions = ["air","desert","air","water"]

I have not yet decided on the conditions.
The default namespace for ids will be minecraft.

So husk can be husk but burned from Rotten Creatures need to be rottencreatures:burned.

I will not be creating seperated lists based on unique conditions. Conditions will be checked after a mob is selected.

I may do a config settings based on different conditions where a mob is chosen based on certain conditions.

[Spawn.water]
chance = 0.1
discardIfNotChosen = true
id = "drowned"

[offbeat-stuff]

This will only be adding mobs that extend ZombieEntity.class
