This method reads all the metadata markers from a file, and returns a collection of the markers.
For Exif files, this metadata collection will contain all the Exif and GPS comments, stored in APP1. It will also contain the audio information stored in APP2.
If the file contains no marker, then this method will return an empty collection.
