ph-css parser cannot parse pseudo class containing attribute selector

I tried parsing has() pseudo class containing attribute selector which failed.

Like has(name='a') {} which is valid. But looks like has() isnt supported at all, and this combination issue could exist for existing supported pseudo classes

The main issue here, are the relative selectors that are currently not supported: https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_selectors/Selector_structure#relative_selector

So fixing this one together with #88 - sorry for the delay. Will be part of the 7.0.3 release
