* Split the SGP30 baseline into 2 values
- According to the SGP30 datasheet, each eCO2 and TVOC baseline is a 2-byte value (MSB first)
- The current implementation ignores the MSB of each of the value
- Update the schema to allow 2 different baseline values (optional, but both need to be specified for the baseline to apply)
* Make both eCO2 and TVOC required if the optional baseline is defined
* Make dump_config() looks better
* Add support for SGP30 eCO2 and TVOC sensors
* Added test for SGP30
* Lint issues fixed
* Lint fixes
* Fixed light lengths
* Cleanup
* Add support for Sensirion SCD30 CO2 sensors
* Fixed few lint issues
* Lint fixes
* Fixed line ending for lint
* Cleanup
* Refactored float conversion
* Refactor unnecessary return
* Refactoring and cleanup
* Updated uptime_sensor_ referencing and simplified checking on availability of copensation
* Temperature and Humidity source moved to a separate compensation block; Dependency for Uptime sensor removed.
* Both humidity_source and temperature_source are now mandatory if the compensation block is defined;
* Clean up
* Cleanup
* Cleanup in search of perfection
* Use correct comment style
