[MoM] Update mutated animals to match vanilla changes

Summary

Mods "[MoM] Update mutated animals to match vanilla changes"

Purpose of change

When I first started adding mutants, the idea was that animals would mutate over time (moose becoming tusked moose, etc). The current conception is that zombies mutate individually, but living beings mutate generationally, so time to update MoM for that.

Describe the solution

Make a biokinetic cow that's not mutated, but has some powers. They have a higher chance to have hodag babies than the normal mutant chance (5%) at 25%. Make baby hodags. Make normal pigeon eggs become pigeon passenger chicks 5% of the time. Make normal chicken eggs become cockatrices 5% of the time. Push back the spawn timers for all of these animals based on how long they would take to become adults.

Bandersnatches, gremlins, fear hawks, and hidebehinds do not need any updates because they aren't mutants, they just have psychic powers.

Describe alternatives you've considered

Testing

Teleported around, messed with time, etc. Normal pigeon eggs could produce pigeon passengers, baby hodags appeared, and so on.
