Mirror bonsai's IfcImporter.process_element_filter so the streamer walks only IfcElement (plus IfcProxy on IFC2X3/IFC4), drops IfcFeatureElement except IfcSurfaceFeature, and routes elements with more openings than the configurable void limit through a second iterator pass with disable-opening-subtractions=true.
