       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.
