Allow fmt::format and friends to use colors

Would it be possible to add a color specifier to fmt::format, fmt::vformat just like it is possible with fmt::print and fmt::vprint? I'm having an issue where I only want part of a string to be colored, so I'd like to wrap it in fmt::format and pass the colored result to a fmt::print, but currently that is not possible. I thought about changing it myself but it required more changes than expected and I don't fully know how the code works.

Great library, by the way!

Here we go #994, I'm looking forward for your feedback.

Perfect, thanks! That was way less code than I expected; it's a good thing you did it and not me. 😅
