Deuteranopia friendly theme

Description

Added deuteranopia-friendly-theme.
This is inspired by #357 of github roadmap.

Intended Outcome

I have also updated the theme README with a screenshot of how a person with Deuteranopia will see the stats. The screenshot is taken with the help of a color blindness simulator

No clue why Prettier task failed, the same happened with #269
This time I even made sure that the spacing is fine.
Maybe some git attribute on my local is causing this issue.

@DenverCoder1 : It is because of the README update, I think it is better to have both views in the README, one with a regular user, and one with the "End User" (User with Deuteranopia)

It is because of the README update

Yeah, the table column widths changed so Prettier is suggesting to increase the widths of the other rows as well. Don't worry about it. I can run the formatter to fix it.

Thanks for the contribution, the images seem to be a bit off-center and have some of the border cut off, you can avoid that by simply doing a right-click > copy image on the demo site and pasting it here.

I've gone ahead and tested it out so here are some images that can be used. The second is generated from the same site you mentioned.
