Migrate data deduplication into python library

[rwalek668]

We want to be able to run this grouped together with the data scraping/preprocessing. We also want to be able to run this separately from the other steps in the workflow.

This will be complete when:
data_processing2.py is converted to a python class
An executable is created to run just the executable portion of data_processing2
The execution of data_processing2.py is linked into the larger data pipeline through an classmethod call.
