Voluminous Energy v1.20.4-0.5 Alpha 1

This is the first Alpha for 0.5. This release contains minor rebalancing but is mostly under-the-hood optimizations. With recipe changes in 1.20.2, it wasn't feasible to backport this to 1.20.1, sorry! Please backup your worlds and report any bugs you find.

Changes

• Animal Fat now drops from all Sheep colours, Dolphins, Llamas, Mooshrooms, Pandas, and Polar Bears
• Rebalanced various Hydroponic Incubator recipes, mostly regarding crops
  • Most crop outputs now produce 9 items
• Further optimize recipes, with a "V2" Recipe Cache implementation, port to 1.20.2+ Recipe changes in vanilla
• Major refactoring to most Recipe JSONs
• Optimizations for the Blast Furnace (Closes #114)
