2D Raycaster Engine

Traditional 2D raycaster engines run on the CPU, so they have a bottleneck when loading screen textures from the CPU to the GPU for each frame. This raycaster engine is implemented using compute shaders, allowing it to avoid this bottleneck since it runs on the GPU.

Textures belong to Wolfenstein 3D.

Raycaster codes are taken from Lode Vandevenne's tutorials and adopted.
