(Sixel) image display support #195

Is your feature request related to a problem? Please describe.

Yes. I'd like to be able to design a graphviz .dot file. Ideally only that, and have that being automatically displayed as graphical version in the slides. you can use the graphviz's dot tool to convert to png, which in turn can be converted to Sixel (there seem to be even Golang-sixel packages available already). So writing .dot file inline in my presentation and have it displayed properly graphed would be awesome.

Describe the solution you'd like

Given the possibility to write my digraph in my .md file, I want slides to transform that to sixel and render it inline in the terminal. support for sixel can be discovered at runtime, so a fallback to, say, boxart could be implemented optionally.

Describe alternatives you've considered There's no alternative except not using slides, which would be sad :)

Additional context

I want to use slides to create a series of slides I can talk along with to share some knowledge (terminal stuff, actually, so using slides would just be natural :) )

NB: I tried preprocessing, but that seems to fitler out control codes (most importantly 0x1B escape character). So I cannot inject custom VT sequences to work around such limitation.

Hey, I believe this is a duplicate of #2 (feel free to reopen if I am mistaken)
