Add a way to download a picture with its updated exif
linked to !245 (comment 1798984649)
We now have ways to update some metadata (headings, and later positions and more) but only in the database, so we would need a way to be able to download a picture and update the exif tags in the meantime.
The initial idea would be to have something like /api/pictures/:id?updated_metadata=true
to get it.
In the initial idea the stored picture would never have its exif updated (only the downloader of the picture would get it), but that may be discussed.
