Strip out z dimension on geojson uploads

[spwoodcock]

Describe the bug

• We don't need z dimension in any of our geojsons.
• Some software includes this in coordinates, e.g. part of a polygon: [[54, 45, 0], [[55, 45, 0]]]

Expected behavior

• We should remove the z dimension somewhere in postgis_utils and try to standardise all geojson usage.

@spwoodcock can you provide me geojson having z coordinates ? that will be great help 🙏

I actually got this requirement from a geojson you sent me 😄

I was never aware the z dimension was included in the geojson spec!

Oh really didn’t quite look into those coordinates 😂

Closing, this is handled by standardised GeoJSON parser
