The hash itself should be file name that contains its collisions. e.g., 6b5a3864635ba9cb.col.

The reference for duplicate references should contain the position and not the hash. Currently, the reference record is src_hash,move,target_hash but to account for collisions this needs to be src_position,move,target_position. This is due to Zobrist being a one-way hash which we can only use for table hashing simply because it will experience collisions.
