Simplify remote control integration with TSOP98638 and STM32F031K6

/*!
 * @file main.c
 * @brief IR2 Click example
 *
 * # Description
 * This example demonstrates the use of an IR 2 click board by showing
 * the communication between the two click boards configured as a receiver and transmitter
 * using the NEC protocol.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger and displays the selected application mode.
 *
 * ## Application Task
 * Depending on the selected mode, it sends a desired message using NEC protocol or
 * reads all the received data and displays them on the USB UART.
