[1pt] PR: Updates for pkgs pillow, idna and openpynx

[RobHanna-NOAA]

Two recent dependabot PR's came in, one for upgrading the pillow package and the other for upgrading idna. Both have been adjusted in this PR.
In this PR, we also moved openpyxl package, which was part of an independent dockerfile, Pipfile and Pipefile.lock in the "dev" directory. This is now merged into the parent standard docker image.

A small update to the README.md was also updated for an unrelated topic (about AWS S3 credentials).

Changes

• Pipfile / Pipefile.lock: As described above.
• data/ble/ble_benchmark/README.md: Updated notes to remove talking the specific ble docker image.

Removals

• data/ble/ble_benchmark
  • Dockerfile: removed in favor the parent root Docker files.
  • Pipfile: removed in favor the parent root Docker files.
  • Pipfile.lock : removed in favor the parent root Docker files.

Testing

• Created a test new docker image, opened it up and ran fim_pipeline on 05030104. I did not test the code for creating, preprocessing benchmark data. Testing for that will come later and can not reasonably be tested here.
