Update IO_I2CDFPlayer.h

Browse Source 
Added SETAM, set the audio Mixer command to the supported EX-Rail commands.
the audio mixer can now be set at startup by using the configuration in myHall.cpp and it can be modified in an EX-Rail scripts.
Syntax:  PLAYSOUND(<vPin>, 0, <am>, SETAM)
Valid values for <am>: 1 or 2
