Assign above-grade height for apartment units

[joseph-robertson]

• Add geometry_unit_height_above_grade=auto under Geometry Building Type RECS in options_lookup

You might consider setting a value in ResStockArguments for apartment units based on the type/size of MF building and where the unit is located (lower, middle, or upper story).

Probably more straightfoward for upper vs middle story (where there could be multiple middle stories)?

First step might be to try different heights (e.g., 0, 8, ..., 24) to understand how much impact this has. Then could think about using average values for different building heights.

Should impact wind speed / infiltration. See NREL/OpenStudio-HPXML#1685.
