Adding your own recipe types

Third-party mods or datapacks can register their own recipe types by dropping a JSON layout file under assets/<namespace>/kjsgen_layouts/ (slot positions, decorations, and a template string with {slot:KEY} / {inputs} / {outputs} / {param:KEY} placeholders), or by firing a Java codegen handler off RegisterRecipeTypesEvent on the mod bus.
