Add printColor directive

[ArielMejiaDev]

How this PR adds value

I tried to answer as much questions as possible in this repo, and I learn a lot in the process, I think this PR would reduce issues related to background colors consistency.

it would be useful to avoid many developers adding issues like this in the future #10 (comment)

PR Content

it adds a directive for css printColorAdjust property:

It would be useful as some designs with tailwind CSS require this property to get an exact replicate of how colors look in a view.

it adds a param so anyone can also set this css rule as exact or as economy to print pdf with more or less colors

I can imagine someone creating a feature with a report that could be printed based on a query strings like this:

$printColors = $request->printMode === 'economy' ? 'economy' : 'exact';

return pdf()->view('reports.sales', compact('colorMode'))->download();

In blade view:

@printColor($colorMode)

<h1 class="mb-4 text-3xl font-extrabold leading-none tracking-tight text-gray-900 md:text-4xl dark:text-white">
    Sales Report
</h>

<table>
//.....
</table>

Thanks for your work on this.

I like the added docs on backgrounds, but feel that the Blade directives are a bit overkill. Could you remove them from this PR?
