CN-GPU: it's so different that's no longer CN-ish

I think i'll add them but Monero v9 will be the high priority fork,
since, as you may have observed, i've very very little dev time left this year.
Everything is getting a fork it seems. Well understood you surely have stuff you have to do that isn't
about developing the miner, or even tech-related at all. Just wanted to say your work is appreciated.
Thank you.
