Lua LPD8806

Port of Adafruit's LPD8806 library to Lua for use on the awesome ESP8266 Wifi module running the Lua-based nodemcu-firmware.

Usage:

LPD8806 = require('LPD8806')
-- number of pixels, data pin and clock pin.
lpd = LPD8806.new(32, 3, 4)
lpd.setPixelColor(0, 128, 0, 0)
lpd.show()

See https://github.com/nodemcu/nodemcu-firmware#gpio-new-table--build-20141219-and-later for pin numbers, they're not what you expect.
