[gdal-dev] Problem with TopoJSON in 3.4.0 c/w 3.2.2

[Simon Eves]

I just tested our stuff against 3.4.0 and immediately hit a problem with
one of our standard example files, which I thought was a GeoJSON, but it's
actually a TopoJSON.

3.4.0 seems to report the field "id" twice, and therefore we try to create
that column twice, and the import aborts due to the duplicate name.

Below is the link to a TGZ with the JSON file and the output of "ogrinfo"
for 3.2.2 and 3.4.0.

The extra line in the field list at the top is obvious.
