Driving WS2811, WS2812 and other NeoPixel devices from ESP8266

An experimental build is now up at:

https://github.com/espruino/EspruinoBuil­ds/tree/master/ESP8266

This has the following extra function:

var esp = require("ESP8266");
var pin = new Pin(1);
esp.neopixelWrite(pin, [255, 255, 255, 0, 0, 0, 128,128,128]);

The array can be as long as you like but must be multiple of 3 in size. The pin is the Pin id of the pin you are using for the data line. The timing is hard-coded for the neopixel speeds.

@tve ... I like the idea but am not yet seeing how it would work for NeoPixels which appear to be our focus de-jure. At the NeoPixel level we want a pixel to be 3 bytes/pixel ... with 8 bits for red, 8 bits for green and 8 bits for blue. Not yet sure how we would turn that into a digital vector ....
