[feature] add Join trait

[after-ephemera]

It would be nice it ColoredString implemented Join so you can join slices of ColoredStrings.

Thanks for the issie @after-ephemera! I looked at the documentation for Join and you can only implement it on Rust Nightly right now, and I'd likewise probably end up holding off on implementing it.

Would the Add trait be acceptable for you? Then you could do stuff like ColoredString + &ColoredString, which I feel like would be a more common use case as well.

What do you think?

[after-ephemera]

Yeah I think Add would be absolutely sufficient for this kind of use case.

Hello I came into here looking for a join method as well. I have a vector of ColoredString which I need to put into one giant ColoredString. Currently I have it set up like this

    let mut buffer = String::new();
    for part in colored_strings {
        write!(buffer, "{part}")?;
    }
    buffer

and I am hoping to return a ColoredString instead of a String.

It might be worth implementing FromIterator
