PeerPressure smoothed

An probabilistic cellular automaton, as [described on my blog (DE)](https://blog.strangerthanusual.de/blogposts/kunst_peer_pressure). There is also a blogpost with [more details about the video generation](https://blog.strangerthanusual.de/blogposts/peerpressure_videos). [Code is on Codeberg](https://codeberg.org/GKnirps/peerpressure) This is a Gauss-filtered version of the automaton, because otherwise the video file would be gigantic.
