autocrafter does not invoke on_craft callback, resulting in invalid results

[fluxionary]

e.g. the recipe for crafting a written book + an empty book to create a copy of the empty book results in empty written books. also, crafting moretrees coconut milk (coconut + axe + drinking cup) eats the axe for similar reasons.

see this approach i took for the unified_inventory_plus "craft all" button for an outline of how to do this correctly, though it will need to be adapted to pipeworks (e.g. the autocrafter doesn't have a real "crafting grid" inventory).

There's some other things that should be considered before/while doing this.
