Wrong NeoPixel bytes

[dastels]

adafruit_seesaw.neopixel.NeoPixel defaults its byte oprder to GRBW.

adafruit_neokey.neokey1x4.NeoKey1x4 lets it do that when it should be setting an order of GRB in the NeoPixel constructor call to match the pixels on the neokey1x4 board.

It looks like this PR:
adafruit/Adafruit_CircuitPython_seesaw#102
fixed things, but changed behavior to break things elsewhere. Similar issue here:
adafruit/Adafruit_CircuitPython_NeoTrellis#18

The fix is simple (just specify pixel order). But may be worth fixing in main library. Opened new issue here:
