Removing External CSS

[mnakalay]

Hello,

I just stumbled on your library and I really like it.

I was thinking about the way it works and I believe there is an additional check that should take place on the generated CSS. The critical CSS shouldn't contain any remote resources like fonts from Google or anything else like that. Otherwise, it just impacts performance the same way normal CSS would.

Take care, Nour
