Fix Y103 command (play_pcm)

Browse Source 
* The parameter is the number of times to loop, e.g. Y103,2: will play
  the sound twice. This still does not work on Windows because
  PlaySound() does not support specifying the loop count.
* Get AMSE data size from its header. This fixes audio glitch at the end
  of sounds.
