Add rx_streamdummyheader command (#1442)

* add rx_restream_stop command. This allows to send a ZMQ dummy header any time user wants to do so. For example this allows to pre-configure the ZMQ processing software before the acquisition begins. Therefore, the dummy header was adapted in order to contain the fields stored in the receiver.

* renamed command, changed inherit, moved commands to zmq related section

* update filename in restreamstop

* renamed helper function, sorted header fields alphabetically

* fixed fnametostream set

* renamed functions, add SetFileName method, format JSON parameters order

* added python bindings and formatting (does nothing really)

* renamed restream stop functions to stream dummy

* checkout .github files from ed8c885

* release notes
