Title: Implement HLL++ offerHashed

Currently, HyperLogLogPlus only implements offer(Object) which only allows user to use its own MurmurHash hashing.
Implementing offerHashed(long) allows users to use their own 64bit hashing.

I left offerHashed(int) untouched since HyperLogLog++ is designed to use only 64bit hash function.
