Add support for image/jpeg mimetype (#1742)

In practice, this plugin does not work to remove embedded jpg images.

On further inspection, it's because the plugin is looking for
image/jpg, which I'm not even sure is a valid mimetype. Inkscape uses
image/jpeg as the mimetype for embedded JPG images.
