Based on the alternatives mentioned, I think console seems the most popular and maintained one of them all.

This is the only blocker for now: console-rs/console#154

In the lunatic-log crate I merged a PR that switches to yansi: lunatic-solutions/lunatic-log-rs#7.

Maybe we should use the same here? Automatic detection can't work either way in WASI, there is no API that allows you to look up what OS/terminal you are running on.

We could always default to one and then dynamically re-encode escape characters on windows during the "write(0, ...)" calls. However, this would be a bit too much work at the moment.
