Fix: 🐛 Contradicting argument configurations

[KP64]

Right now, there are the following output coloring options:

 /// Turn on colorization always
#[arg(short = 'C', long)]
pub force_color: bool,

and

/// Print plainly without ANSI escapes
#[arg(long)]
pub no_color: bool,

This allows Users to contradict themselves when passing arguments like this:

cargo run -- --no-color --force-color // It will force the color btw

Which is why I've come with the following solution:

#[derive(Clone, Copy, Debug, clap::ValueEnum, PartialEq, Eq, Default)]
pub enum Coloring {
    None,
    #[default]
    Colored,
    Forced,
}

and

#[arg(short = 'C', long, value_enum, default_value_t = Coloring::default())]
pub coloring: Coloring,

This also allows Users to specify the coloring output they want with “-C” alone, making it more intuitive.

This is much better. Thank you! Could you also update the usage section of the README to reflect the new arguments? I can update this part of the readme later once this is merged.

Alright, I think I've done it. Have I missed a section or anything?

I would suggest "auto" instead of "colored". Maybe also add a long alias --color.

Indeed. This would probably be better. I'll change it right away!
