Allow match weight threshold for `cluster_pairwise_predictions_at_threshold`

[RossKen]

Is your proposal related to a problem?

cluster_pairwise_predictions_at_threshold is currently only supported for match probability, given how much we use match weight as evidence of a match it feels like we should have an option for match weight as well.

Describe the solution you'd like

Add parameter to cluster_pairwise_predictions_at_threshold called threshold_match_weight to filter by match weights.

There will also need to be some logic/warning if users enter values for both threshold_match_probability and threshold_match_weight

Describe alternatives you've considered
