Basic minifier

[CosmicHorrorDev]

Resolves #17

This is by no means a perfect minifier, but it's simple and certainly good enough for most cases you'll see with ANSI styling

This PR stubs a minifier in between munching the ANSI codes / text and converting it to HTML. The minifier works by condensing all of the input into tidy chains of text and ANSI codes. Then it runs a pass over all the input and discards any runs of ANSI codes that wind up with the same style as the last set

There's a snapshot test included that should act as a good demo. The input text was taken from running the following with some manual replace-all'ing of the ANSI codes to get a more human readable format

use ariadne::{Color, Config, Label, Report, ReportKind, Source};

fn main() {
    Report::build(ReportKind::Error, (), 34)
        .with_config(Config::default().with_char_set(ariadne::CharSet::Ascii))
        .with_message("Incompatible types")
        .with_label(
            Label::new(32..33)
                .with_message("This is of type Nat")
                .with_color(Color::Cyan),
        )
        .with_label(
            Label::new(42..45)
                .with_message("This is of type Str")
                .with_color(Color::Blue),
        )
        .finish()
        .print(Source::from(include_str!("sample.tao")))
        .unwrap();
}

sample.tao

def five = match () in {
	() => 5,
	() => "5",
}

def six =
    five
    + 1

Thanks! I won't get around to review this today, since it's release day for Pomsky, but it's on my radar.

[CosmicHorrorDev]

All good! I'm in no rush :)

Sorry for the delay, busy week :)

I'd like to rewrite this code using a more functional approach, using Iterators to avoid allocations. But that doesn't block this PR. Thanks for working on this.
