deserialize / serialize method for HH (frequent items)

[sundeepks]

Hey,

Thanks for creating a rust binding for datasketch, I was looking for the same to use the datasketch between java & rust project

If possible can you provide a support for Deserialise / Serialise method for HH ?

Hey @sundeepks ! Thank you for your interest. I'm unfortunately a little to busy to provide support for new features, but I'd be happy to help review if you'd like to implement it and merge the PR.
