- make sure we call run() before checking for errors, we will miss status update otherwise and lock the sensor class in the error state that it cannot recover from
- set error flag only when either bsec or bme680 report an error. ensure we show any issues reported by the library via the debug log

TODO: add custom error messages through virtual method?

Also, a minor fix to the sensors test when using 1m and 2m boards

Add support for BME680 using libalgobsec proprietary algorithms for precise Indoor Air Quality (IAQ) measurement. Unlike traditional CO2 sensors - and good ones are expensive - it measures nearly all VOCs compounds in the air (plus other gases) and compensates those measurements with its built-in temperature and humidity sensors to determine indoor air quality.
