ed196c70e5 Sort biomes by their id to avoid indeterminism from wrong ordering. 
Fixes part of #158. There still seem to be some problems left.

d7f0796abd Fix lag spikes when moving after all the terrain has loaded. 
The solution was simply to cache the side data of chunk meshes instead of regenerating all sides on update.
This probably makes first-time loading a bit slower due to requiring making more copies of the mesh data, but it's not a big deal.

Fixes the remaining half of #94.

94e4fc5269 Speed up the function that checks which chunks need to be added or removed from the RenderStructure. 
Now it only checks the surface chunks, meaning it's now O(r²) instead of O(r³), where r is the render distance. There might be an even better way, but I don't see it yet.

Sadly the performance stays constant due to updating the visibilityMask each frame. But if I find a better solution for it then there should be some great improvements here.

9e45e0e662 Remove some dead code and leftover things from my last commit. 
Now there is only one mutex left inside the process for updating and rendering chunks on the client-side.
This is a bit of a step back here. A lot of processes are now locked to the render thread.
Once I implemented lighing #61 I will need to look for better options.

49179d0891 Fix #151 
It seems that this was caused by setting the `pos` to undefined, but all my code assumed that it was `.{0, 0}`.

e398824cab Refactoring: Use const instead of var where possible. 
When I started to use zig, I mostly used `var`. But over time I adapted to using `const` where possible which is more readable and the compiler is currently optimizing it better.

c2a955f86c Scale textures and models in LOD terrain to match their true scale. 
This also adds some support for rendering larger volumes of voxel models at once. That might allow greeding meshing for voxel models.

9978fd2025 Move all the C files to a seperate repo. Also use precompiled binaries to reduce first-time compile-time. 
Resolves #110
Resolves #117 (I did however decide to use static linking, I had some issues with dynamic linking)
Also getting closer to #118

Additionally this avoids the problem caused by https://github.com/ziglang/zig/issues/17652 since harfbuzz is precompiled.

0c2d309f2a Ditch mach-freetype: now building freetype and harfbuzz directly. 
Having zig bindings was certainly nice to have, but overall the code isn't too different really.
One nice advantage of building freetype and harfbuzz directly is that we can get rid of some unnecessary dependencies, like brotli.
Also, since that was the only zig dependency outside the standard library, this finally gives me the freedom to update zig whenever I want.
This is a necessary step for #117.

Resolves #139

2f52e9923b Render voxel models using a separate shader. 
This allows simplifying the regular shader, improving its performance by ~10%. #96
It does however increase the number of separate draw calls by a bit.
Additionally this opens up more opportunities for the future, in regards to drawing regular models. #134

044ab3bb62 Rework the fog, so it doesn't need the alpha component anymore. 
This also fixes #93 as a side effect
This could also theoretically improve performance due to using a smaller image format, but I couldn't measure a bit difference on my computer, it might be that my driver/hardware just pads the alpha component.
