Use NDJSON data format instead of CSV

[mike-feeney]

The data transformation scripts output both CSV and NDJSON files. We can convert the site to using the NDJSON directly instead of using Papa Parse to convert the CSV data into objects.

Larry went over the data and how it compiled together. Larry went over the NDJSON format, requested a change over.

Mike changed frontend so that instead of papaparse to parse the csv, it just uses vanilla javascript to parse NDJSON directly. The pull request is here!
