Excel to csv files

[clairblacketer]

The goal is for the dashboard to read off of four csv files specifying the checks (table, field, and concept) and the description of the checks. It is difficult to keep up with four files so it would be nice to have a mechanism that reads in the excel file and create the csvs from that.

@clairblacketer , would also be nice to remove empty lines from the CSVs:

Closing this - ultimately it is less error prone to keep the four CSVs for now.
