Improve reliability through continuous VCP analysis using INA239 and ATmega328P

/*!
 * @file main.c
 * @brief VCPMonitor4 Click example
 *
 * # Description
 * This example application showcases ability of Click board
 * to be configured for different readings and read temperature, 
 * voltage, current and power.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of communication modules (SPI, UART) and 
 * additional alert pin. Reads Manufacturer and Device ID,
 * Configurates device for reading all device measurements.
 *
 * ## Application Task
 * In span of 500ms reads and calculates data for IC temperature,
 * Bus voltage in V, Shunt voltage in mV, and current and power for device.
