Show EXIF data of selected media file in metadata editor #5535

The media files usually contain EXIF data that might be helpful to be visible directly in Kitodo.Production. When a page/media file is selected in the metadata editor the EXIF data could be read from the image and displayed in a designated area, e.g. aside the image in the detail view or in the metadata column.

If so, then you should be able to display all metadata (basic image metadata, IPTC, EXIF, and XMP). There are Java libraries like pixymeta that can be used to read (and also write) image metadata. I think it would make sense to implement this in a way that [a configurable choice of] the image metadata is copied into the technical metadata of the METS file, where you can display it in the metadata editor. (As an outlook, in a second step, you could then also edit them there and have them written back into the images. But that should not be part of this development task.)
