ipa: raspberrypi: Add sensor temperature to DeviceStatus

Add an optional sensor_temperature field to the DeviceStatus structure. If a
temperature measurement is available for a frame, the value is returned out
through the SensorTemperature control in the Request metadata.

Additionally, provide the sensor temperature value from the std::ostream &operator<<
overload.
