Display recording of tokei running

[XAMPPRocky]

As a followup to #290 it would be preferable if instead of text there was a display tokei running on a directory. This was previously done with asciiema but I no longer want to use this service, and would prefer an alternative.

Initially I thought of making a gif however making a gif that is high quality of tokei running would take up a relatively tremendous amount of space and I would want to avoid that both for when people clone the repo as well as when they download to view it on the GitHub README.

Video file formats would be small however they do not display inline on GitHub and to my knowledge there isn't a well supported gif like format that works across all browsers.
