Track indoor air conditions with ENS161 and STM32F031K6

/*!
 * @file main.c
 * @brief Air Quality 11 Click example
 *
 * # Description
 * This example demonstrates the use of the Air Quality 11 Click board 
 * by reading and displaying the calculated Air Quality Index according to the UBA and ScioSense, 
 * and equivalent TVOC and CO2 concentration.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of I2C and SPI module and log UART.
 * After driver initialization, the app sets the default configuration.
 *
 * ## Application Task
 * The demo application displays the Air Quality Index of the UBA information,
 * concentration of the TVOC and CO2 and Air Quality Index according to ScioSense.
 * Results are being sent to the UART Terminal, where you can track their changes.
 *
 * ## Additional Function
 * - static void airquality11_display_aqi_uba ( void )
