Sometimes after a hard reset of the ESP the SCD30 needs a long time until returning the first measurement. Resetting it after startup seems to fix this behaviour.

Log every measurement to the serial console, but return only `true` in `processData()`(thus starting further processing like CSV, MQTT, LORAWAN) if the data is reliable (stable measurements, CO2 > 0) or the sensor measures too low CO2 values (< 250). The latter condition should be reported, because the user can then initiate a manual calibration procedure.

Ongoing investigation showed that the sensor does report 0 ppm only after startup, i.e. in 'BOOTUP' state. We check for this condition in `hasSensprSettled()` already, so there is no need for this state anymore.
