Range offset drift over temperature

Selfheating or a change in ambient temperature increases silicon temperature, which results in a range offset drift.

This may be minimized by performing a periodic autocalibration, resulting in a typical drift of 0.15 mm/°C.

The autocalibration is done automatically when a new ranging session is started. A stop/start of the device is

required if the device is already streaming.
