Configure and read out the Raspberry Pi gas sensor (MQ-X)

The calibration is started automatically during initialization. It is important that the sensor is in good / fresh air as smoke / other gases would falsify the calibration. The process takes a few seconds, but the gas content can already be measured thereafter (see video). Some sensors are quite hot, but this should not be a cause for concern.
