geojson_intersects_feature does not work with geojsons containing null geometries #236

Open pnorman opened 4 years ago

pnorman commented 4 years ago

Using the config files in #227, I get an error with this geojson

Like #235 this isn't critical because I can drop these items, but RFC 7946 and the 2008 GeoJSON spec explicitly allow the member with name of "geometry" to be a JSON null value.
