使用XM125和STM32G431RB增强项目中的存在检测和液位测量功能

 * @file main.c
 * @brief PCR Click example
 *
 * # Description
 * This example demonstrates the use of PCR Click board by 
 * reading distance between Click board and object. 
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger and performs the Click default configuration.
 *
 * ## Application Task
 * Reading distance between Click board and object every 2 seconds and logging it on UART terminal.
