Add processing tools for exclusion sets

[egrace479]

This is for test-set filtering, removal of human faces, removal of images of labels (vs. specimens), removal of empty camera trap frames (from GBIF), general cleaning for citizen science data (remove cluttered occurrences and set camera traps to proper processing), etc. in more detail...

• All lookup table exclude creators from TreeOfLife-dev (many of these are here) should be in src/ for this repo:
  • PDQ hash process
  • Image type separator (museum, camera trap, and citizen science categories)
  • Museum Specimen processing: label vs specimen filter
  • camera trap processing: megadetector & reducer
  • citizen science image processing
  • face detection
• Add slurm scripts that run these processes from TreeOfLife-dev to root-level scripts/ directory (these will be more template (your/path/here) style.

This whole process then also needs clear documentation for how to use each of these tools and the pipeline.

Adding these to a processing/ folder at the repo root in #27 to be worked into the package. This does include documentation explaining the code and the repo format at this stage.
