feat(present): add audio output (#382)

* feat(present): add audio output

This PR adds the necessary audio output to the presenter mode, so it can play audio contained in video files, see #375.

However, this does not fix the issue that slides do not contain audio by default, but should be solved by Manim, see #375 for updates on that topic.

* [pre-commit.ci] auto fixes from pre-commit.com hooks
