Rust OpenGL OpenXR example

Minimal example code to display a triangle on both desktop and in OpenXR using OpenGL in Rust. Also provides session_create_info() to perform appropriate platform-specific magic to get SessionCreateInfo. One should use caution when using this library, as it was really just hacked together using guesswork and std::mem::transmute(). PRs welcome!
