V2 Can we remove CssParser.convert_uris

[stoivo]

I am looking to try to remove the use of regex and wonder if we can remove if feature completely CssParser.convert_uris

https://github.com/premailer/css_parser/blob/ab52436dbe238faeffffd0d08710f567c84fcf69/lib/css_parser.rb#L128-L156

It as added 17 years ago https://github.com/premailer/css_parser/commit/4215785086d550bff69596ee04b63984b7c36c04. I think when it's used in premailer we want to have all absolute urls not relative. If thats the reason we should that code should probably be in premailer instead.

Maybe we should just keep it to reduce the braking changes. Just want to ask
