removed the need to provide the pin argument for Esp8266 NeoPixelBus where it was ignored. Added another DotStar color feature. Fixed DotStar color features to use RgbColor when there is no need for RgbwColor.

// This example will cycle between showing four pixels as Red, Green, Blue, White
|
|
// and then showing those pixels as Black.

// Included but commented out are examples of configuring a NeoPixelBus for
|
|
// different color order including an extra white channel, different data speeds, and
|
|
// for Esp8266 different methods to send the data.
|
|
// NOTE: You will need to make sure to pick the one for your platform
|
|
//
|
|
//

// There is serial output of the current state so you can confirm and follow along
