Add the option to add geojson components to globes, from geojson files. One geojson file creates one GeoJsonComponent, which in turn may contain multiple GlobeGeometryFeatures
Geojson is a format that supports points, lines, and polygons. In addition to the basic functionality, extra features have been added that will long-term allow rendering the geometry needed to represent KML files (another format for geospatial geometry data). Here are links to references for both formats:
Geojson: https://geojson.org/
KML: https://developers.google.com/kml/documentation/kmlreference
data/assets/examples/geojson includes some example files that I have used for testing. Any geojson file can also be added through drag-n-drop. Note however that you might need to change the AltitudeMode or HeightOffset properties for the feature to be visible.
