gym/wrappers has removed "Monitors" and are using "RecordEpisodicStatistics"

I got this error while running README.md. Stack Trace:

iex(1)>

This states that we can no longer use monitor.hpp. We need to have something similar to RecordEpisodeStatistics. This issue is helpful.

Thanks for the detailed issue report, is that something you like to look into further, or should I create a patch for it?

I have already started some work on it, if that okay with you?
