Added option for 100% o2 calibration:
For the implementation of the selection of the calib gas the reactivation of the menu elemen "FIELD_TOGGLE" was necessary. Within the calibration menu item it is now possible to select between air and 100% o2 calibration. The calibration itself no consideres the ambient pressure during calculation of the coeff.
