How to use the latest Pyodide for Pyxel Web
Since the latest Pyodide supports SDL2, I'd like update Pyxel Web to work with it instead of the modified version, [pyodide-sdl2](https://github.com/kitao/pyodide-sdl2).

Any help is welcome for that.
@pmp-p, I would appreciate it if you could give me some advice.
