使用ISOW7743和STM32G071RB隔离并加强SPI数据

/*!
 * @file main.c
 * @brief SPI Isolator 8 Click example
 *
 * # Description
 * This example demonstrates the use of SPI Isolator 8 Click board™ 
 * by reading the manufacturer ID and device ID 
 * of the connected Flash 11 Click board™.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of SPI module, log UART, and additional pins.
 * After the driver init, the application enabled both isolated sides of the device.
 *
 * ## Application Task
 * The demo application reads and checks the manufacturer ID and 
 * device ID of the connected Flash 11 Click board™. 
 * Results are being sent to the UART Terminal, where you can track their changes.
