Modified file cfg.h by introducing #define EXTENDED_RANGE_50CM.

Settled StartMeasurement by removing MeasureData_t from parameters.

Settled range single shot measure and als single shot measure.

Settled GetMeasurement by introducing range_single_shot case and als_single_shot case.

Settled VL6180x_AlsSetThresholds by introducing the computation in order to pass

the arguments in lux and write the same arguments in raw device value into registers.
