使用RFD77402和STM32G431RB快速精确地测量距离

 * \brief LightRanger3 Click example
 * 
 * # Description
 * This app precisely measure distance without making actual contact.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes driver init and configuration chip.
 * 
 * ## Application Task  
 * Includes measurements, reads distance, and logs distance to USBUART for every 300 ms.
 * Distance measurement at distances ranging from 100 mm to 2000 mm.
