Title: Make HyperLogLog.addHash public

I need to add already hashed values to an existing HyperLogLog value in my proposed change to SetDigest (https://github.com/facebook/presto-facebook/pulls/hermanventer). Making addHash public would be just perfect for this scenario and it seems like a generally useful thing to do.
