rsaber: Beat Saber clone written in Rust

State

We are really at the beginning. At least, the colored notes are already moving and there is a basic collision detection logic :). As there are no built-in levels, they are fetched from https://beatsaver.com/.

Supported Devices

Actually, any headset with OpenXR support + Vulkan API is supposed to work.
