* This is a "Library" of sorts, where I have made several (admittedly basic)
* functions based off of the original examples provided. Currently these are aimed at
* displaying what I'll dub "Pixols", the 2D array that contains the pixels and RGB
* values resulting from using the python image converter.
*
* You can flash this directly to your pixel to see a demonstration of each
*
* Note that this does not interact with the MPU
