Partial craft support in custom Data Pack recipes!

I was messing around with the 1.16 data packs and I tried creating a custom recipe for cooking salmon.

Basically one salmon in a bucket and one coal would yield a cooked salmon. This isn't intended to be fair nor balanced, I was practicing custom crafts.

The water bucket seems to be consumed no matter what, and I thought partial crafts would be a cool addition to the game.

Here's how the recipe looks like:

Here's my suggestion for partial crafts:

In a way, this would allow custom recipes to craft more than one type of item at a time, which could lead to chaotic recipes if poorly handled. I believe the "byproduct" parameter could be optional due to how json files work, though I'm not entirely sure on that part.
