After the fixes in #13728
, it is now possible to extract EXIF data from JPG, JPEG, and PNG images. It would be good to support EXIF extraction for all images tagged as is_image in the Document model.

To achieve this, a refactor of DOCUMENT_TYPE_MAP and DOCUMENT_MIMTYPE_MAP is needed to define the allowed image types for EXIF extraction to allow tiff,tif and clean up of other image types.
