Integrate Physics

[heyx3]

There doesn't seem to be any existing integration in the style of GLFW.jl or ModernGL.jl. The closest I can find are these options:

• Going through Python's well-developed Bullet3 API: https://juliapackages.com/p/pybullet
• Automatic generation of a DLL for interop: https://github.com/SimonDanisch/Bullet3Builder/releases
