sensor never leaves FORCED_MODE #9

I've been looking through the code in detail, and there seems to be something odd with get_sensor_data(self). The power mode is set to FORCED_MODE at the start, but is never returned to the mode it was in when starting the method. Is this intentional? Or should the mode be saved when entering this method, and reset just before returning?

FORCED_MODE should trigger a single measurement and then reset to 0.

The data sheet says:

Single TPHG cycle is performed
Sensor automatically returns to sleep mode afterwards
Gas sensor heater only operates during gas measurement
