Achieve infrared remote control with TSOP38238 and PIC32MZ2048EFM100

/*!
 * @file main.c
 * @brief IR Click Example.
 *
 * # Description
 * This is an example that demonstrates the use of the IR Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization driver enables - GPIO and Log. 
 * 
 * ## Application Task
 * This example contains two parts :
 * - Transmitter mode - Sends data using NEC protocol.
 * - Receiver mode - Reads data that is been sent using NEC protocol and 
 *                   displaying it on the UART terminal.
