Exif write registered coordinates to images files.

After I have registered a terrestrial 3D scanner project I update the registration to the individual scan files so that I may import individual scan files in the correct coordinates. 

Similarly it would be useful if after alignment was completed RC was able to write the new determined camera positions to the image Exif.

In my case I have aligned a project to OSGB coordinates using ground control points.  I will extract the point cloud from RC for drawing purposes but will need to give something to the client.  Autodesk Recap is the preferable client viewer.  As this software is not the best at image alignment it would be useful to give it a hand with accurate camera positions.

I think I can export a flight log from RC but unfortunately cannot import this into Recap.

PS original image files are rough GPS.
