Version 3:
* moved another memory block into AHB RAM, giving more room for
* stereo buffer.
* moved content of decode() to main()
* decoding is now safe to be called multiple times (bug in older versions)
* Output routine now fills stereo buffer, DAC output sums channels,
* just for demonstration that stereo output could go here
