This series adds support for the Sensirion SCD4x sensor. 

The driver supports continuous reads of temperature, relative humdity and CO2 
concentration. There is an interval of 5 seconds between readings. During
this interval the drivers checks if the sensor has new data available.

The driver is based on the scd30 driver. However, The scd4x has become too 
different to just expand the scd30 driver. I made a new driver instead of
expanding the scd30 driver. I hope I made the right choice by doing so?
