Mimic @januz's dictionary with 35k variables

[wibeasley]

@januz had a very very wide dataset that REDCap had problems producing the CSV for. But the JSON was well-formed. The changes made in #335 work now on his machine, but we'd like to include a similar dictionary to detect any regression errors in the future.

I'll probably

• simulate it now with a big loop to spit out the csv dictionary, and then
• throw in some flavor from his real dictionary (that shouldn't be public)

@januz, I used the adapted text that you approved. If you'd like any other features in the dictionary, either start a new issue (and reference this one), or just add it to the code that generated the dictionary:

Sounds good. Thanks, @wibeasley!
