updated ZS head
Some missing IIngredient#getInternal implementations
recipes.replaceAllOccurences now supports an optional parameter that specifies recipes for which outputs shoudl be changed (uses IngredientAny in case no output was provided)
Loaders now can be delayed/frozen until the mod that froze them calls the frozen alias. This should allow for mods to prevent a loader from being loaded to early by other mods. They now need to subscribe to the load_finished event, if they want to get the post-finished loader stage though.
Added blockstate handling
Fixed NBT matching (again!)
Fixed recipe removal
