External neo pixel using pin A1 doesn’t work

[sajingeo]

When using an external neo pixel on pin A1 (as suggested in multiple posts on adafruit.com) the neo pixels don't light up.

This is due to lines 70 to 84 (Adafruit_CircuitPlayground.cpp) that re-map A1 for cap touch - even though there is nothing mentioned in the H file about its usage.

Fix:
comment out line 70 to 84 if you are not using cap touch.

or

Circuit playground begin() should be overloaded when you pass an external neo pixel pin.
