neopixel_spi v03
Created By: Ivan Yohuno
SSID: 200717683

Notes:
-Code to be run on WS2812 neopixel LEDs, can run with a single pixel or a strip of max 8 leds connected together
-Single LED can be connected to power source of 5V but if connected to 5V logic will need to be shifted up from 3.3V to 5V

Features:
-SetRGBPixel // sets colour of one RGB Pixel (the first pixel connected), generally used for testing. Colour is a mix of 3 8 bit values of red, green and blue
-SetRGBStrip // sets colour of RGB strip of 8
-setRGBStrips //sets colours of 4 RGB strips of 8 
    colours 2D 4x3 matrix:
    {{room 1 strip red, room 1 strip green, room 1 strip blue},
     {room 2 strip red, room 2 strip green, room 3 strip blue},
     {room 3 strip red, room 3 strip green, room 3 strip blue}
    } 
-SetRGBPixels // sets an RGB strip of 8 to individual colours using a 2D 8x3 matrix
    colours 2D 8x3 matrix:
    {{1st pixel red, 1st pixel blue, 1st pixel green},
