Implement CURL

Hello! It's great to know that you implemented CURL. I also implemented CURL in my small repository few months ago(https://github.com/Cerphilly/SimpleRL).
If you're interested in training RL algorithm by image, have you considered implementing DBC(Deep Bisimulation for Control) in tensorflow 2?
I tried to implement DBC in tf2, but it didn't work for some unknown reasons and I couldn't find it out.

Hello @Cerphilly ! Thanks for letting me know your repo!
I haven't tried to implement DBC, but I'll take a look into the paper and try to find time to look at your code.
