Support Sensirion SGP30 and SGPC3 multi-pixel I2C gas sensors
Supported Features:
* Indoor Air Quality (IAQ) concentrations for
- tVOC (in_concentration_voc_input)
- CO2eq (in_concentration_co2_input) - SGP30 only
IAQ concentrations are periodically read out by a background thread
to allow the sensor to maintain its internal baseline.
* Gas concentration signals
- Ethanol (in_concentration_ethanol_raw)
- H2 (in_concentration_h2_raw) - SGP30 only
