Added pressure compensation to CO2 detection:
A pressure compensation is needed if the ExplorIR shall be used under extended pressure conditions. The procedure recommended by the application note has been integrated. To keep things simple the focus of the CO2 measurement is not the precision, as it is needed for the decompression calculation, but the indication of a critical increase of CO2 in the breathing loop. That's why only a lookup table with 1000ppm steps has been implemented instead of calculating the polynom for every measurement.
