(Relevant notebook: https://github.com/codeforboston/clean-slate-data/blob/master/notebooks/Categorize%20Charges.ipynb? → check the code) This should take the comprehensive master crime list from mass.gov (https://www.mass.gov/lists/district-court-complaint-manual), convert to PDF, and join with the prosecution data sets. Which is the final converted PDF?

@laurafeeney - why do we want this as a PDF?
