Hashie::Mash deep_merge is super O(2^n) slow about hashie

[masatomo]

This issue is actually critical. Without this patch, a request with just 10 elements of array takes more than 30 seconds.

I strongly recommend to merge this patch and release new version of Hashie asap. We are using the @davemitchell's forked repo until this is merged. (thank you so much for this patch, @davemitchell !)

Yeah I second that. Just did a bundle update on another gem and along came Hashie 2.0.5 - specs became 10x slower all because of Hashie. Took me two hours to understand what happened.

@jch @wapcaplet @markiz @craiglittle @7even @jimeh @davemitchell hey guys this issue is a big one really, this pull request shouldn't just be sitting here for months. 2.0.5 is unusable in it's current state.

Sorry, I was helping, but I lost access after leaving Intridea. The project
doesn't seem actively maintained, perhaps it's time to find a new
maintainer?

I am taking over. The fix has now been merged on master and I will make a release this week after I've gone through all the pending PRs.
