Add wolf puppies

[Steppewolf-CDDA]

Summary

Content "Allow wolves to reproduce, add wolf puppies"

Purpose of change

Several other wild animals could breed, why not wolves?

Describe the solution

Allowed wolves to breed once a year in spring to create up to 6 puppies. They will become (even more) aggressive if you go near the puppies. You can tame wolf cubs but not full-grown wolves.

Describe alternatives you've considered

If leading away a wolf puppy and raising it as a pet is infeasible, I'm fine with removing that part.

Testing

Created puppies, made sure they flee from the player and can be tamed.

Additional context

Apparently it's possible, if a wolf is raised in captivity from puppyhood, for it to become attached to a human. I'm not fully sure if it's feasible to depict realistically without a more in-depth pet system, but pigs work this way already in game.

EDIT: made them untameable as requested due to realistically, still, being harder to tame than a stray puppy.
