Add a way to ignore a specific embedded data

[FransTwisk]

Love this plugin, and want to use it, but I need a way to ignore removing certain embedded data, maybe by adding a specific comment behind the property?

Sorry for a very long delay.

Right now I can suggest this plugin: postcss-separator. It has ability to split up code by regular expressions for value, property, rule, media query.

I want to add this feature in my plugin, but don't have enough time.
PR is very appreciated.
