Make API to extract sound stream

[Baekalfen]

We don't current have a way to get the sound output through the API. This could for example be in the form of a buffer to copy at every frame.

This might also require some work to separate the sound implementation from SDL2.

Hello, I would like to work on this issue.

That sounds great! Do you need an introduction to it?

Is this still active? I would like to give it a try.

I don't think it's being worked on, no. But you're very welcome to give it a try. You can ask on our Discord, if you need any help.
