Function moltenvk_deps::check_or_install

pub fn check_or_install(install: Install) -> Result<PathBuf, Error>

This will check if you have the Vulkan SDK installed by checking if the VULKAN_SDK env var is set. If it's set then nothing will happen. If it is not set then it will download the latest SDK from lunarg.com and install it at home/.vulkan_sdk. It will then set the required environmnet variables. You can install silently or with a message. Use check_or_install(Default::default()) for an install with a default message
