Title: Move BuildResidentialHPXML measure to option-based arguments
Description: Refactors ResStock to use the new BuildResidentialHPXML measure, which now has ~100 options instead of ~600 detailed properties as arguments. Also moves much of the ResStock special sauce around configuring the HPXML models into the ResStockArgumentsPostHPXML measure. The options_lookup.tsv file is now significantly simpler.
