NOTE:
5.6.5.6
This function performs a capacitive measurement on all enabled sensors. The measured signals
for each sensor are then processed to check for user touches, releases, changes in rotor angle
and changes in slider position.

Arguments
current_time_ms
Return
Value
uint16_t
NOTE:
5.6.5.7
This function forces a recalibration of all enabled sensors.

This functions initializes all the configured sensors, performs calibration.
All sensors must be configured (using qt_enable_key or qt_enable_rotor or
qt_enable_slider) and initialized by calling qt_init_sensing before calling this function.
