10ms clock stretching is not sufficient for the SCD30 CO2 sensor
Sensirion tells us the following:
Clock stretching period in write- and read-frames is 30ms, however, due to internal calibration
processes a maximal clock stretching of 150 ms may occur once per day.
Fix: increase the clock stretching capabilities to 150ms
