Color( green, red, blue)? #185

Even in strandtest.py, the colorwipe starts at color green, then red, when the code says it should start with red then green.

while True:
        # Color wipe animations.
        colorWipe(strip, Color(255, 0, 0))  # Red wipe
        colorWipe(strip, Color(0, 255, 0))  # Blue wipe
        colorWipe(strip, Color(0, 0, 255))  # Green wipe

The default strandtest probably assumes a ws2811 based led strip with the colour order of red, green, blue.

Wa2812 leds with the integrated controller expect a colour order of green, red, blue.

The https://github.com/jgarff/rpi_ws281x/blob/master/python/examples/SK6812_strandtest.py example shows how to set the strip type.

The strip types are defined in https://github.com/jgarff/rpi_ws281x/blob/master/ws2811.h
