Experience the art of signal convergence with TMUX1208 and STM32F031K6

/*!
 * \file 
 * \brief MUX 3 Click example
 * 
 * # Description
 * This application sets multiplexing one input channel to eight single-ended output channels. 
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enable's - GPIO, also write log.
 * 
 * ## Application Task  
 * This is an example which demonstrates the use of MUX 3 Click board.
 * Sets the current active and changes the channel every 1 sec.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * All data logs write on Usart Terminal changes for every 1 sec.
