Suggestion: Support asciinema recordings #145
Description
Currently, we can do that manually by pressing ctrl+z and invoking asciinema play and then going back to the presentation with fg.
It would be great if we could put something like this in the slide:
[asciinema:80:24:./demo.json]
This tag would create a rectangle of 80 columns and 24 lines to play the recording. Clearly this involves some kind of terminal emulation, which could be achieved more easily with something like libvterm
