change the import CRS for metadata

Hi,

today with drone RTK, we have directly the metadata in national CRS and not in CRS WGS84 with EGM96.

In France for example, we are in RGF93 and with RAF20. And cause to that, we can't use metadata directly. We need to import photo position manually.

And it cause a lot of trouble from customer who use other software as PIX4D and metashape.

Today, we can change the display of CRS but not the import.
