Allow to get the geometry of Ifc Structural analytical model items

[zhukoven]

Describe the bug 📝

I need to display IFC classes relating to Structural FEM model, but it seems that Fragment engine does not currently support them:

• IfcStructuralAnalysisModel
• IfcStructuralCurveMember
• IfcStructuralSurfaceMember
• IfcStructuralCurveConnection
• IfcStructuralPointConnection
• IfcStructuralPointAction
• IfcStructuralLoadGroup
• IfcStructuralLoadCase
• IfcStructuralLoadPlanarForce
• IfcStructuralLoadSingleForce
• IfcStructuralPlanarAction
• IfcStructuralPlanarForce
  ... and maybe some other structural classes.

Model building_01.ifc (https://github.com/IfcOpenShell/analysis-models/blob/master/ifcFiles/building_01.ifc) in ThatOpenViewer:

The same building_01.ifc model opened in BlenderBIM:

Steps to reproduce 🔢

1. Download test IFC FEM files from IfcOpenShell repo: https://github.com/IfcOpenShell/analysis-models/tree/master/ifcFiles
2. Try loading these files with ThatOpen viewer: they seem to load, but no geometry is shown to the user.
