We can bring in additional relation mappings through these qualified predicates: https://github.com/biolink/biolink-model/blob/master/predicate_mapping.yaml

First, we need to generate a TSV from that YAML file that has columns identical to https://github.com/ExposuresProvider/cam-pipeline/blob/kg-tsv/ro-to-biolink-local-mappings.tsv, with the addition of one more column containing some kind of structured qualifier information. We'll use that generated TSV in Souffle kg script.
