GeoJSON to FloorSpaceJS method for footprint

[kflemin]

1. Go from GeoJSON footprints to FloorSpaceJS models. Users can then subdivide the footprint and assign space types, then reimport the FloorSpaceJS models back into UO and use the more detailed geometry in UO analysis.

2. Also, as part of this effort, please review the current FloorSpaceJS UO Workflow to determine if the OSM model is still required (in addition to the floorspaceJS). Adjust as needed, adjust the documentation, and potentially relax the file extension requirements on the Detailed_OSM field)

Do we want to focus on supporting this first, or a workflow to go from OpenStreet Maps to GeoJSON? There seems to be a script to do this, we could work on integrating it to the SDK? This could be useful for the prototype district workflows as well.
