[QGIS-Developer] loading images in QGIS Viewer with RPC modelisation

I tested with development version [0] but I think it's already working
with previous one.

To check if it's displayed according to RPC, you could display
OpenStreetMap XYZ tiles beneath your image and check if your image is at
the right place.

The SCR (in QGIS right bottom corner) should default to 4326 and your
coordinate should be lat/long in degrees. If the RPC isn't read, you
should have coordinate in pixel instead.
