Failed to run on Windows 11 (both wsl2 and native)

I tried to use `midiloop` on Windows 11 via `wsl2`, and it tries to use ALSA, but it (obviously) can't find it.

When using native Python 3.13, I'm able to `pip install .` in a venv (after installing a few things, including MinGW), but at runtime I get:

```

```

Is `midiloop` supposed to work on Windows 11? It looks like RTMidi doesn't support virtual ports on Windows. Is there another backend that does?
