Changes

This effort is a complete reimplementation of a shader pipeline that should be compatible with all shaders in [https://github.com/libretro/slang-shaders slang-shaders], including the preset parser, the shader preprocessor, and SPIR-V translation, as well as runtime implementations for Direct3D 11, OpenGL, and Vulkan. To be clear, librashader does not “rip out” the shader parts of RetroArch and just repackage it up, but is a complete reimplementation with a [https://docs.rs/librashader/latest/librashader/ fully documented Rust API] that exposes every part of the pipeline.
