Combadge example only plays once for CP Classic (AVR)

[caternuson]

This line added a pin config change to end():
https://github.com/adafruit/Adafruit_CircuitPlayground/blob/master/utility/Adafruit_CPlay_Speaker.cpp#L41
and nothing in the loop() of the combadge example turns it back to output.

Example sketch can be fixed by adding a call to .speaker.begin() in the loop(), but not sure if this behavior change was intended for the library.

Looks like it was some of the refactoring from begin() to playSound() here:
https://github.com/adafruit/Adafruit_CircuitPlayground/blob/master/utility/Adafruit_CPlay_Speaker.cpp#L74
That used to just call begin() which would set the pin back to output.

Fixed now (1.8.2 or later), thanks for spotting this.
