Convert cleaning script to Python

[newswim]

We have all of the inputs and outputs from the previous correspondence with the Uni of Michigan, so we should be able to build a dictionary which can be used in a function as part of the cleaning process.

This function's type signature would look something like:

normalizeStatute :: dirtyStatute -> cleanStatute

This workflow includes:

1. Normalizing statute information
2. Other things (@normaljosh can you describe the other parts here?)

Currently this:

• converts the datetimes to use hyphens instead of slash
• gets the earliest charge date
• maps charge names to the generalized umichigan decsriptions
• labels the primary charge

Still need to:

• Put the motions in there
• Define has_evidence_of_representation
• Other misc cleaning stuff emily's script does

[normaljosh]

re: motions, it seems like we iterate through all the events and if one of them contains one of these "good motions":
('Motion To Suppress', 'Motion to Reduce Bond', 'Motion to Reduce Bond Hearing',
'Motion for Production', 'Motion For Speedy Trial', 'Motion for Discovery', 'Motion In Limine')

then they get added to the motions field, and has_evidence_of_representation becomes 'true'
