Give the sensor some time to adjust Display the applied offset on the webpage, not just the parameter

Previously, it was hardcoded to 2000 ppm, which remains the default value.

A soft reset of the SCD30 sensor, i.e. calling `SCD30.reset()` was added in commit fe023428 to force an instant update of the measurement interval after bootup. It seems, however, that the calibration value is not stored if the sensor is reset before carrying out at least one measurement after calibration. This breaks calibration with the current code, because the ESP (and then the SCD30) is reset directly after calibration.

* Trying 10s instead. * Adding warning if timestep < 10s Forced calibration should hopefully be more reliable now.

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.

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.

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.

This state is showed with red waiting LEDs. Previously, the state 'BOOTUP' with blue waiting LEDs was used to show invalid measurements. Use blue waiting LEDs now only during sensor acclimatization.

The SCD30 sensor has a response time of 20 s to reach 67 % of its final reading. The first measurement can thus be unreliable, if the environment changed shortly prior to startup. Set measurement interval to the shortest possible value (2 s) and wait then, until the measurements have stabilized. Show a blue led effect in the meanwhile.
