          Sends command *data* to the remote *target* discovered in the
          most recent call to one of the sense_xxx() methods. Note that
          *target* becomes invalid with any call to mute(), sense_xxx()
          or listen_xxx()
  
          Arguments:
  
            target (nfc.clf.RemoteTarget): The target returned by the
              last successful call of a sense_xxx() method.
  
            data (bytearray): The binary data to send to the remote
              device.
  
            timeout (float): The maximum number of seconds to wait for
              response data from the remote device.
  
          Returns:
  
            bytearray: Response data received from the remote device.
  
          Raises:
  
            nfc.clf.CommunicationError: When no data was received.
