v0.7.0

This release once again, extensively overhauled the vec3 class. I removed the dependency on the xsimd library, and chose to use SIMD intrinsics directly.

I also changed all the header guards to #pragma once, and made a bunch of smaller code quality changes.

As such, this release doesn't add many features (if it adds any at all), but focused on improving code quality of what is already there.

v0.5.0-alpha.3

This release saw an extensive overhaul of the vec3 class. I added comprehensive constexpr support to the class, as well as used SIMD instructions to speed up the computations being done at run-time.

0.4.3-alpha.2

Added multithreading into the renderer with a simplistic but functional multi-core render function.
