Achieve precise presence sensing and motion detection with TPIS1S1385 and PIC18F57Q43

/*!

 * \brief Presence Click example
 * 
 * # Description
 * This application enables usage of sensor for motion and presence sensing
 * and measuring of object's and ambient temperature.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes driver and performs the click default configuration.
 * 
 * ## Application Task  
 * Checks whether a new event (motion, presence or over-temperature) is detected. 
 * If there's no event detected it reads the ambient and object temperature and displays
 * the results on the USB UART.
