Asciinema Support For My Blog!

I often want to have console output in my blogposts. Since I don't want to upload videos, due to their size, I just create code boxes.

<asciicast src='/media/demo.cast' />

Which is then automatically turned into this:

This partially happens at generation time and partially at runtime. The goal is to avoid loading any additional JS or stylesheet if possible.
