Add a way to send all important metadata without exif
For the moment, we posting a picture, we support all exif/xmp metadata + override_capture_time/override_longitude/override_latitude
It would be easier to also support all fields needed by the tag reader:
So I'd say
override_picture_type=`flat|equirectangular`
override_direction=some float (and always consider that it's the true north
This way, it's easier for clients to set them (without finding the correct exif/xmp tag), we can set several exif/xmp tags if needed, and we can handle simple float conversion for the direction.
When this is handled by the API, those fields should be added as CSV column in the CLI.
