       Metadata file source and sink blocks (Tom Rondeau)

       Two  new blocks implement enhanced file source and sink blocks that incorporate metadata passed using the
       stream tags feature in GNU Radio. It is now possible to store things like frequency and sample rate  into
       capture files, or whatever key/value pairs you tag onto data streams inside a flowgraph.
