Feature request: register_ldtk_entity_tag::<TBundle>(tag: &str)

[Syynth]

I believe it's possible to do something like this already manually, but it would be very helpful to have a convenient way to register a bundle to be inserted on each entity based on the tags associated with that entity.

I'm imagining a system similar to the LdtkIntGrid macro, but even just a simple system that did not allow access to the other entity instance data would be very valuable for me.
