BuildResidentialHPXML measure: Load custom geometry

[joseph-robertson]

The idea is to use, e.g., OpenStudio::Model::Model.load(osmPath) to load custom geometry instead of using create_geometry_envelope to create geometry.

List of current requirements on custom geometry:

• Surfaces and subsurfaces must have "Index" features populated on OS:AdditionalProperties objects.
• The following methods use get_adjacent_to where the "Standards Space Type" field for OS:SpaceType objects must be populated with HPXML locations (e.g., living space, attic - unvented, basement - conditioned, etc):
  • set_roofs
  • set_rim_joists
  • set_walls
  • set_foundation_walls
  • set_floors
  • set_slabs
  • set_doors
• Must describe a single unit of the building. (What happens if it describes the whole building? Related to Allow modeling whole SFA/MF buildings #1376?)
