Avoiding ANSI in Amber, use Rust to inject it

> It might be nice to include a color library in std to avoid literal ANSI in Amber scripts. I've found [owo-colors](https://github.com/owo-colors/owo-colors) to be nice on the Rust end of things 🙂

So this is a library that writes ANSI code in pure Rust, we can think of to create a builtin to print with colors and avoid to implement those in Amber/Bash and use that library.
