Christoph Schultz	8a063e7c27	Add support for setting the range and autocalibration. Closes #1. ... * added possibility to set Range, to enable/disable Autocalibrate and to calibrate maually ( see Datasheet v 1.2 : https://www.winsen-sensor.com/d/files/MH-Z14A.pdf * Update MHZ.cpp * Update MHZ.cpp * Update MHZ.h added calibrate Span, for complete functionality but commented out , due to professional use (req. constant atmosphere with 2k, 5k or 10k ppm CO2.). corrected the bugs in MHZ.cpp also. * Update MHZ.cpp Added comments for Sensors with specific firmware.
