Companion PR: resstock-estimation #129 (new PR)

Removes the artificial cap of 3 stories for MF buildings, and instead uses RECS data to allow for up to 21 stories. Horizontal location and level tsvs were updated to account for the new dependencies. ResidentialGeometryCreateMultifamily was also updated for error checking and to set the Middle-level units at the halfway point. Dependency options in the Window Areas and Geometry Garage tsvs are updated as well.
