Downlink — get data sent to a multicast group

According to the v0.17 description, the command returns the frames sent to a multicast group for a period. The current ONS version has no such command: the server responds to the request with an invalid_command_req message.

Request and response: get_multicast_data_req → invalid_command_req.
Access: the command is not executed with any token.
