    tracker: Support GRL_METADATA_KEY_START_TIME
    
    Indicates the offset of a logical resource inside the file that
    contains it.
    
    Support situations where multiple logical resources are contained
    in one physical file. This allows us to support multiple audio files
    contained in one .FLAC file and indexed with a cue sheet, for example.
