object-door-instance.json files not automatically created for the inset_generator

[Samuel-Wiest]

Textx automatically generates 5 .json files from the .floorplan file (coordinate, floorplan, shape, skeleton, and spatial relations). To create the tasks using "floorplan generate /config.toml -i /input_folder", the scenery builder also requires an object-door-instance.json for each door. This must currently be created manually (they exist for the hbrs floorplans, but not for other example floorplans or for custom floorplans). Automation would be preferred.
