Ability to generate dark and light hex colors with a new optional luminosity option

[nickjj]

Currently we can run Faker::Color.hex_color to generate a random hex color. It does not support any arguments.

It would be great if we could optionally run:

• Faker::Color.hex_color(luminosity: 'dark')
• Faker::Color.hex_color(luminosity: 'light')

To simplify the interface this option could default to random. There's other potential values that could be interesting too like bright or pastel but let's not get too crazy from day 1.

If this option existed it would be very easy to generate very nice looking random user avatars. It's common nowadays to generate a random color that is a circle and use the user's first name's initial in place of a photo by default. Darker colors tend to look much better here for that circle and this new feature would let us generate dark colors as needed.

The Python version of Faker has this behavior at https://faker.readthedocs.io/en/master/providers/faker.providers.color.html. I used the word luminosity based on their documentation as it's pretty much the perfect word to describe what this is.

Currently there's no workaround other than to not use this gem's hex_color generator and instead generate a custom color manually.
