* For the prefix_removal, the image names have 'MICH-V-' prior to the barcode, so that is used for matching
  but removed for output.
* There is also code active to replace the LLM-predicted "Catalog Number" with the correct number since it is known.
  The LLMs to usually assign the barcode to the correct field, but it's not needed since it is already known.
