Cross Platform GFX Library

This is work in progress to add an API similar to wgpu in that it abstracts atop lower level rendering APIs such as OpenGL and Vulkan to allow use of both.

I mainly want to do this to test my abilities and so the current OpenGL work isn't entirely scrapped. But ultimately, the #26 will likely become the main backend for performance.

I've been purely working on the OpenGL backend of this new agnostic api (been a massive undertaking and pain)
Guess I underestimated it too much to make a ticket for it
