* 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 Co-authored-by: Otto Winter <otto@otto-winter.com>
