Discovery<=>SmallCPU inferface update:
The sensor data struct is extended to store the data of up to three (three visible O2 sensors). To avoid unnecessary payload on the SPI only the last update sensor data item is transfered. The sender receiver uses the sensor ID which is provided in parallel to identify the correct storage location.
