MiniAudio

I am asking to add the generator to include [MiniAudio](https://github.com/mackron/miniaudio) because it is a nice cross platform audio solution that isn't bulky I have generated binding myself for it before but now that I have moved to silk.net for Vulkan and OpenXR I would like to sort of bring all of the native libraries I use together into silk I will work on trying to add the generator with silk.net generator system mind you a don't really have experience with it I have used [ClangSharp.PInvokeGenerator](https://www.nuget.org/packages/ClangSharp.PInvokeGenerator/) and also used clang sharp directly to make bindings to steam audio
