Would it be possible to have add_if_not_contains?

[craigschmidt]

Your library looks great. My use case is in deduplication, so I would be wanting to know if a given string is already in the Bloom filter, and add it if not. I can certainly make a call to contains, and then a call to add_str, but it seems like that will be repeating computing all the hash values. I assume it would run roughly twice as slow as a combined function could. Would that be something that would be possible to add? It would return whether it was added or not. Thanks!

Hi @craigschmidt , sorry for not noticing this issue. I submitted some code to implement the add_if_not_contains method, do you see that it meets your needs?
