Add Text Coloring via CLI flag

[o2sh]

By default, the info_lines' title (Project, HEAD, Pending, Version, etc) are colored based on the first color of the dominant language:

       let color = match self.colors().get(0) {
            Some(&c) => c,
            None => Color::White,
        };

It would be cool to let the user customize the text coloring via CLI flag, something like onefetch --text-color X X X X

This flag would work similarly to --colors except that it would only affect the text coloring.

The user would be able to provide up to 6 colors that would change the text colors in this order: title (red), ~ (green), underline (orange), title (maganta), colon (yellow), info (cyan)

Hello, I'd like to take a shot at this. I'm guessing a lot of lines in info.rs are gonna be modified...
