Expose raw IAQ (indoor air quality) levels as an AQI (air quality index) sensor. Might be useful for downstream applications doing their own calculations.
Add basic handling for the non-linear nature of the IAQ scale used by the BME680 gas sensor.

As it turns out, the IAQ (indoor air quality) index used by the BME680 gas sensor, is not linear. Great... 馃憖
The first implementation #7286 assumed a linear relationship between IAQ level and TVOC density, and that obviously wasn't correct. This is an attempt to improve the overall accuracy of the conversion, and align the estimated TVOC density to its corresponding IAQ level.
We'll have to keep in mind, that we're dealing only with estimates here, and not with lab-grade sensor readings.
