Why?:

• Quick item to enforce lowercase columns in regulators.cftc.cot(). A small number were not being handled correctly.

What?:

• Update transform_data section.
• Update the cot_ids.json file with a couple of missing items.

Impact:

• Improved consistency.

Testing Done:

• Do something like, obb.regulators.cftc.cot("all", report_type="supplemental")
• Columns like, "pct_oi_nonrept_short_all_nocit" or "ncomm_postions_long_all_nocit", should now be in all lowercase.
