Usage:

python compute_contamination_metrics.py --input-data <input_data> --scenario-data <scenario_data> --output-stats <output_stats> --input-format <input_format>

For instance, you can call this with The Pile, e.g. have:
    input_data  = 00.jsonl (download https://pile.eleuther.ai/)
    scenario_data = (example included with repo, but can use HELM to generate)
    output_stats = arbitrary output file name, e.g. "output_stats"
    input_format = the_pile
