I noticed that the similarity score results can contain duplicates.
The reason is that if a candidate pair appears in more than one block, they will produce more than one similarity score.
This PR introduces a simple unique value iterator to remove the duplicates from the similarity scores stream. The stream is already sorted, so duplicates will appear one after the other.
