Upgrade data acquisition process with MCP3428 and PIC18F57Q43

/*!
 * \file 
 * \brief Adc3 Click example
 * 
 * # Description
 * ADC 3 Click represent 16-bit multichannel analog-to-digital converter. 
 * The click has four pairs of screw terminals onboard, letting you access the chip’s four differential input channels.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Application Init performs Logger and Click initialization.
 * 
 * ## Application Task  
 * This is an example that shows the capabilities of the ADC 3 Click 
 * by taking voltage measurements from all four channel. Results are being sent to the UART Terminal 
 * where you can track their changes. All data logs write on USB UART and changes for every 1 sec.
