2.0.0

Port to Minecraft 1.21.11 on NeoForge 21.11.

• Rebuilt on NeoForge's new transfer API: proxies now expose and traverse the ResourceHandler/EnergyHandler capabilities that replaced the old IItemHandler/IFluidHandler/IEnergyStorage trio in NeoForge 21.11.
• The api package changed accordingly: the item and fluid merger handlers are replaced by NeoForge's CombinedResourceHandler, the energy merger is now MergerEnergyHandler, and the two filter wrappers merged into a single generic FilteredResourceHandlerWrapper.
