Ensure `BFIndex` is pickleable #605

Open

It's currently not possible to pickle the BFIndex, while the Index can be pickled.

import pickle
from hnswlib import BFIndex

index = BFIndex(space="l2", dim=10)

with open("index.hnswlib", "wb") as f:
    pickle.dump(index, f)

It would be nice if both index types could be pickled, how hard would it be to support pickling for BFIndex?
