Feature Request: Add ansi color functions

[stelcodes]

Hi Micheal!
I'm wondering if you'd be interesting in adding a namespace for ansi color functions like io.aviso.pretty.ansi? I love adding color to my cli scripts but I don't think any ansi helpers are included with Babashka at the moment, but I could be wrong. Also copying clansi is another option or maybe including it as a default library with Babashka? Idk what do you think?
