Multipolygons not supported

[mwillumz]

Looking quickly through your source it appears that Multipolygon support is intended... but it appears not to work

see before and after:

Seeing lots of stuff like this in the logs. It looks like GEOS expects linestrings to have a matching start/end point.

The following GeoJSON was seen in the logs. This does not seem valid to me as each ring in the multipolygon only has 2 vertices:
