create tsv illegal relationship_to_oxygen values flagged

[turbomam]

I forget what this was all about.

The DataGood students observed that there are unreasonable relationship_to_oxygen values in ~/biosample_basex_data_good_subset.db

I guess this touches on the question of what the output should be in a repair process when there is no apparently valid replacement value.

See rel_to_oxygen_example script.
