It can take quite a while to record a demo. This patch adds a `--fast` flag for reducing delays to a tenth of the usual. You can play the recording with `asciinema play -s 0.1` to get close-to-normal speed (except that command delays will be slower). That way you can adjust timings with shorter round-trips.
