tantivy requires Scorer to be positioned on a DocId at all time. This decision is not performance neutral. When we have an intersection of a heavy DocSet with a lighter one forcing the positioning of the first doc is needlessly expensive. This PR fixes this by introducing a seek_doc parameter in the weight function. Weights may skip over documents when they create the Scorer.

Can't we require the docid seek on the BlockSegmentPostings instead and drop this intermediate struct?
