Dev Bugfix: Alignment problem in lifedata structure: Since the introduction of the 64 bit DigO2 sensor ID the potential risk of a misalignment is present in the lifedata structure. E.g. If a new 8bit variable is added in front of the data structure containing the 64bit value. To avoid this in future the sensor data structure which may contain the 64bit value has been moved to the top of the structure (first element)
