Redefine timekeeping for the modern age with PCF2123 and PIC18F57Q43

/*!
 * @file main.c
 * @brief RTC13 Click example
 *
 * # Description
 * This is an example that demonstrates the use of the RTC 13 click board™.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of SPI module, log UART and additional pins.
 * After driver initialization and default settings,
 * the app set the time to 23:59:50 and set the date to 04.08.2021.
 *
 * ## Application Task
 * This is an example that shows the use of a RTC 13 click board™.
 * In this example, we read and display the current time and date, 
 * which we also previously set.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * All data logs write on USB changes every 1 sec.
