[PROJ] WKT1 Vertical Perspective CRS regression

[Jonathan Gale]

Hi Even,

Thanks for your help.  Good to know what was happening.  I'm happy to see that the conversion aspects will work going forward too.

Ah missed that.
Fix pending in GDAL per https://github.com/OSGeo/gdal/pull/3327<https://github.com/OSGeo/gdal/pull/3327>

That worked by accident here as an invalid WKT1 mapping (for the conversion
part) was returned, but which was sufficient to get the information on its
geographic CRS. So worked by accident.
