Changes

Add helper method to create an ingredient from a fluid object

Pretty common request, and the fluid objects without blocks are more awkward to create it as they lack a tag

Ensure all IDs produced by IRecipeHelper are in your own namespace

Tinkers used this to simplify some datagen key creation on Minecraft objects. We never want to generate a recipe for another domain.

Add IdAwareObject and use for a new recipe helper utility

IdAwareObject just represents an object that can return its own ID, similarly to RegistryObject. Simplifies some utilities as they can automatically work with ItemObject and FluidObject at no extra cost
