Raw acquisition mode support for UC3L

The QTouch Library Raw acquisition mode can be used with QMatrix, QTouch Group A and QTouch Group B methods. When raw data acquisition mode is used, once the raw acquisition data is available from the CAT module for all the sensors, the measure_complete_callback function is immediately called with acquisition data (channel_signals).  The channel_references, sensor_states and rotor_slider_values data are not updated by the Touch Library in this mode.
