Support [asciicast files](https://github.com/asciinema/asciinema/blob/develop/doc/asciicast-v2.md) as a new markup via [asciinema-player](https://github.com/asciinema/asciinema-player). For more on asciinema, see the [introduction](https://asciinema.org/). So users can use asciinema recorder to generate an asciicast file (or you can download a sample file from https://asciinema.org/a/335480.cast?dl=1), then upload it to Gitea and play it on Gitea.
