Parse include/exclude markers with @preserve or /*! hints

[xumepadismal]

Some bundlers (in my case it's Angular CLI) minifies CSS before running critters. Therefore, any /* critters:exclude */ comments got stripped.

However, it's possible to preserve them using /*! critters:exclude */ or /* critters:exclude @preserve */ hints but in this case these markers are ignored by critters.

Would it be possible to implement a bit smarter parse logic to support these cases?

Thanks
