 *  ===========================================================================
 *  Just a simple library for VLSI's mp3/midi codec chip
 *       - Minimal and simple implementation (and dirty too)
 *
 *  Modified on 05 September 2015 by Vassilis Serasidis.
 *       -   Added a patch for playing MP3 files on some "LC Technology" VS1053 boards.
