Butcher's Delight items can now be decomposed, including carcasses!

• Ported to 1.20.1
• All meats available through Butcher's Delight can now be decomposed and feature different drop rates depending on cut, animal, and whatever my sleep deprivation told me sounded okay.
• Carcasses can be deconstructed, but take longer than their smaller counterparts. Carcasses take considerably longer to process, but have a chance to give significantly more resources at the cost of additional nutrients and time.
• Skullcow can now be consumed by the decomposer.

Carcasses are designed to have an element of high risk / reward with potentially losing out on resources due to inefficiency, as well as taking significantly longer to digest. Decomposer resource outputs may be subject to change with feedback and further testing.
