Optimization: HyperLogLog.contains_many()
Previously, we were generating a new temporary HyperLogLog key for every element that we wanted to do a membership test for. Now, we're reusing the same temporary key since we copy/delete the HyperLogLog before/after each membership test anyway. This speeds up membership testing by 2x.
