Subject: jpeg-utils: Filter out certain tags from external EXIF file

Turned out that we shouldn't blindly copy all metadata from the supplied
external EXIF file since they belong to a different image. This includes
image size, JPEG compression parameters, rotation etc.

This commit adds tag filtering so that not all tags are copied, retaining
the important ones from the gallery image.

The list of retained tags is by no means complete and is subject to future
tweaks. For the moment this feature is recommended to be turned off (and
is by default).
