Allowed for different textures on each side which can be different sizes. Updated the format of the json models to allow for more control over the model. No parameters of the model are hard-coded any longer, allowing it to be used with any texture on any block.

Also restructured a large portion of the code to make it cleaner and add in many helper classes for future expansion

Proof of concept for loading textures split across multiple blocks, currently is hardcoded texture wise but in the process of making it dynamic.

This is achieved using custom model loaders and baking custom quads with UV data based on their block position.
