Show GPS metadata for video files

Since video files can also store GPS coordinates, it would be great if those were also recognized by Photoview, including showing videos on the map.

It could be done by the command exiftool -location:all input.mp4, which will extract GPS data and convert it to human readable format, or by ffmpeg -i input.mp4 -f ffmetadata - - which will output raw metadata of the video and then we need to parse it to find the location.

Taking into account that the geolocation could be stored in different formats, the 2nd command gives more flexibility.
