Pararelized the wireframe shading mode

I did a bunch of small things alongside it, but the main feature for this devlog is the pararelization of the wireframe shading mode. It was previously fully single threaded, but it wasn’t that hard to pararelize, i just had to make the function it used to write into the framebuffer (draw_line) CAS atomic, to avoid race conditions. Now wireframe is the fastest shading mode in basically all scenarios.
Below, you can see a performance benchmark (built into rasterminal using a flag) with wireframe mode on a super dense mesh and how the wireframe mode looks like (you can also cycle the colors).
