Use EXIF data of image to prefill image description

During attachment upload Pleroma returns a "description" field.

* This MR allows Pleroma to read the EXIF data during upload and return the description to the FE using this field.
    * If a description is already present (e.g. because a previous module added it), it will use that
    * Otherwise it will read from the EXIF data. First it will check -ImageDescription, if that's empty, it will check -iptc:Caption-Abstract
    * If no description is found, it will simply return nil, which is the default value
* When people set up a new instance, they will be asked if they want to read metadata and this module will be activated if so

There was an Exiftool module, which has now been renamed to Exiftool.StripLocation

 ## Added
 - Officially supported docker release
 - Ability to remove followers unilaterally without a block
+- Uploadfilter `Pleroma.Upload.Filter.Exiftool.ReadDescription` returns description values to the FE so they can pre fill the image description field
 
 ## Changes
 - Follows no longer override domain blocks, a domain block is final
 - Deletes are now the lowest priority to publish and will be handled after creates
+- Uploadfilter `Pleroma.Upload.Filter.Exiftool` has been renamed to `Pleroma.Upload.Filter.Exiftool.StripLocation`
