breaking: replace css-tree with @projectwalace/css-parser

[bartveneman]

breaking changes:

• Removes support for printing comments
• No longer lowercases type selectors (STRONG, A) because of a small issue where we cannot distinguish (yet) between a type selector and some other nested identifier-like nodes.

other changes:

• TODO: reduces install size from 2MB+ to ~120kB
• TODO: benchmark how much faster it is now
• TOO: benchmark how much less memory it uses
