Interest in wrapper for SDL_Mutex?

[bobbens]

For a project, I need reentrant mutex, which base rust doesn't provide. Now, it's possible to use parking_lot, but I'd rather just stick to SDL3. So, I've got some Mutex working (basically copied most of the Mutex code for Rust, but using SDL_Mutex instead of a system one).

Would there be any interest in seeing this as a PR? It would basically be a reentrant drop-in replacement for "Mutex". Or should I just keep this local to my project.
