Version 2.0

I finally remembered that this pack exists

• Use scoreboard-based clock to drop the feather items instead of overriding the vanilla gameplay/chicken_lay loot table
  • This means the pack should now be fully compatible with all packs adding chicken variants with their own eggs
  • This also eliminates the Chickens Lay Anything dependency for older game versions
• Chickens now shed feathers in intervals between 7.5 and 15 minutes
