Example: If ("bucket:bucket_water", "bucket:bucket_empty") is a
replacement pair, the crafting input slot that contained a water
bucket will contain an empty bucket after crafting.

- Note: replacements only work correctly when stack_max of the item
- to be replaced is 1. It is up to the mod writer to ensure this.
