mqx: C gas sensors mq2-mq9 Implement a single source file for the following: * mq2: H2/LPG/CH4/CO/alcohol/smoke/propane/etc * mq3: Alcohol/benzine/CH4/hexane/LPG/CO * mq4: CNG (mostly methane) * mq5: H2/LPG/CH4/CO/alcohol * mq6: LPG (mostly propane/butane) * mq7: CO * mq8: H * mq9: CO/CH4/LPG The documentation for these sensors notes that they do not read an exact gas concentration. Some of the sensors have examples for how to calibrate with a 'clean air environment' for outputing ppm, but this is not the case for all mqx sensors. Because of this, the output can be read as a normalized output (0.0->1.0), raw volts (normalized * aRef), or a scaled/offset voltage.
