archive this repo please

there is a mono repo now in place, this one is found here:
https://github.com/FullHuman/purgecss/tree/master/packages/postcss-purgecss

I just got confused about this a little bit, would be helpful to close this repo and reference to the new one.

I understand, sorry about that. I'm looking at moving some issues to the main repo (while avoiding duplicates), and see if I can get a note of the open PRs. I'll add a message on the README to redirect to purgecss in the meantime
