Hybrid search vector per target

[dirkkul]

Adds support for

    objs = collection.query.hybrid(
        query=None,
        vector=wvc.query.HybridVector.near_vector({"first": [1, 0], "second": [1, 0, 0]}, distance=0.1),
        target_vector=["first", "second"],
    ).objects

and

    objs = collection.query.hybrid(
        query=None,
        vector={"first": [1, 0], "second": [1, 0, 0]},
        target_vector=["first", "second"],
    ).objects

It also adds the filename of the test to the collection name - I thought I had duplicate test names and added it. Wasn't the issue in the end but I think it doesn't hurt

Hi is this live and does this signal the beginning of multi-vector search for weaviate?
