scripts/calculate_all_dsra_jenks.py: unexpected EOF and unused? Consider moving to attic?

[anthonyfok]

python/calculate_all_dsra_jenks.py in this repo fails flake8 test with:

./python/calculate_all_dsra_jenks.py:44:241: E999 SyntaxError: unexpected EOF while parsing

There is another copy at OpenDRR/model-factory as script/calculate_all_dsra_jenks.py with different content.

I suspect that this Python script has been superseded by another. If it is no longer used, perhaps it is good to move calculate_all_dsra_jenks.py and other outdated/unused scripts into an "attic" directory (or maybe delete them).

Low priority, code clean-up, putting in the backlog.
