Add example of communication using protobuf messages Add the protobuf example that emulates the work of dummy sensors that send data to the sensor client. The example uses UDP sockets to send datagrams that contain protobuf messages. Messages consist of two layers: - The Type-Length-Value wrapping message that specifies the the message type and allows to verify the message size. - Sensor message that contains a sensor data. The example intends to show how to generate the code from the protobuf schema and use it in simple UDP signalling protocol on both sender and receiver sides. Both client and emulator have simple UI implemented using QtWidgets.
