Apple silicon requires mediapipe-silicon package

[hueachilles]

mediapipe package doesn't exist for Apple silicon. Use/install mediapipe-silicon instead.

This could probably be noted in the README.

I haven't got a apple silicon to test it, does the rest of the code also work on apple ?

On the first setup everything was working. The webcam video was showing in one of the windows and the face points on another. I was able to configure an empty Unreal 5 project with Metahumans to receive the data.

The next day (and following attempts) Unreal was unable to detect the Live Link source. The Python windows still showed correctly and the cli didn't print any errors. I did some light debugging and the service seemed to be running correctly. I'm waiting for Unreal to release 5.1 (not Preview) and I'll try again.
