ETL into pdap/data-intake

[EricTurner3]

ETL Package refactored to read from schema.json file and will now:

• search for agency_id and grab the record
• search for all available dataset_id, insert if they do not exist
• search for data_type, verify it exists, then grab the same named table in pdap/data-intake
• sync the mapping in schema.json to match the columns for the pdap/data-intake table
• output all the modifications (sync) back out to the schema.json file

Still work-in-progress:

• use the synced mapping from the database to actually enumerate the scraped data records and ingest them into pdap/data-intake

Successfully loaded data into DoltHub!

• pdap/data-intake (all the data in the bulletins tables are from this etl process)
• pdap/datasets (two new datasets for the agency)

I updated my settings to Insert NewLines and will do PEP8 formatting and unit tests in the next PR. I just do not want to increase this PR as it functionally is working fine and our pipeline does not currently have specific formatting requirements.
