Milky Way 3.0.0

1.21.1 port!
Milking resources now relies on a datamap for more flexibility; check out here
- Can now make the milk timer configurable on a per-mob basis, and the mod_loaded parameter allows for more built-in compat on releases
  - Right now pre-emptive compat includes Neapolitan, Milk All The Mobs, Buzzier Bees, Goated, Milkable Blazes, Extract Poison, Bovines and Buttercups, and Cobblemon. Only Cobblemon required additional in-code compat, as it depends on a "Milkable" boolean data thing.
  - Compat with Caverns and Chasms (as well as other mods with their own buckets) will return in time. Let's see them come to 1.21 first, yeah
