#2810

change line 195 of SFEMP3ShieldConfig.h from

#define USE_MP3_REFILL_MEANS USE_MP3_INTx

to

#define USE_MP3_REFILL_MEANS USE_MP3_Polled

This changes the driver not to use Interrupts, but rather the main loop() will

MP3player.available();

will do the refill. This however, requires the main loop() not to be blocking.
