Describe the feature

Currently mods like kubejs-create & kubejs-thermal implement their own version of a RecipeJS with fluid ingredients.

It would be great if there were a FluidIngredientJS and if the normal RecipeJS could have fluid inputs & outputs.
That way, there could for example be a FluidInputFilter and a FluidOutputFilter for removing recipes.

Additional info

I would also be open to work on this and open a PR if this is something that makes sense to you
