Add modificaitons to handle complex files

[veronikarichter]

Move several modifications to development that improve the handling of large complex IFC files.

Major Updates:

• Neighbor computation:
  • Modified neighbor computation for models with missing space-to-element relations (add sim_setting for calculation in CreateRelations?)
  • Extend corresponding boundary search for neighbor modifications
• WWR / External Shading (Handling External Walls without Windows)
  • Set WWR to external walls
  • Add fixed shadings to windows
  • Add shading control for WWR-Windows
• Improve healing of space boundaries and removal of collinear and coincident vertices
• Add option to manually initialize the default constructions
• Corrections: Internal/External bounds and normals
  • Add turn horizontal elements internal function
  • Add SB correct internal external function
  • fix horizontal surface bound normals function
• Add option to set adiabatic surfaces to a fixed temperature

Minor robustness Improvements and small features:

• Add additional objects for plates and coverings as these may relate to space boundaries
• Extend renaming the storey names
• Switch shadow calculation to pixel counting
• Increase robustness for missing layersets
• add sim_setting for solar transmittance, solar reflectance, conductivity and airflow permeability of WINDOWMATERIAL:SHADE
• Add simsetting for shading control solar radiation on surface.
• Add output variable for surface shading device is on time fraction
• Extend IDF validation algorithms
• Update setting the construction names / surface type mapping
• Fix get_parents_and_children: opening area assignments
• Extend pyocc_tools
• Add occupant CO2 + output variables
