JsonDedupCounter

JsonDedupCounter counts unique actors via an internal HyperLogLog sketch and exposes add to register one actor. Duplicate actors are ignored.

For numeric increment counters, use JsonCounter instead. Keeping the two roles in separate classes makes invalid method calls (such as increase on a dedup counter) compile-time errors.
