create version that uses deid "pre-defined" header fields to flag

[vsoch]

• create flow into application that doesn't use OCR, but deid
  • should allow for file or folder input
  • output should be choice between png, dicom, with/without summary PDF report
  • files should NOT be overwritten for any reason

Once we have the above, we can test in a headless environment over a folder of sampled images and then use the reports to assess how well we did.
