Word.isColor doesn't support RGBA hex colors

[jwilsson]

• Node Version: 6.11.1
• NPM Version: 5.3.0
• postcss-values-parser Version: 1.2.2

This issue is regarding a problem with:

• Standard CSS
• LESS
• SCSS
• SASS

For example:

color: #000000ff;

Expected Behavior

Word.isColor should be true.

Actual Behavior

Word.isColor is false.

How can we reproduce the behavior?

Run the parser on a RGBA hex color, for example the one above.

This should be a simple extension of the current isColor regex, to allow for colors with 8 chars. I'd be happy to do it.
