Data mapping analysis for Pension Fund Society Tombstone Data

This ticket is used to analyze whether we have the required tables and data structures in the LEAR db and where COBRS Pension Fund Society Tombstone data belongs in LEAR and how to transform the data.

- [ ] Determine if COBRS db extracts all relevant data for filing that need to make it into LEAR db. Reference [data mapping\(COBRS  LEAR\) doc](https://docs.google.com/spreadsheets/d/1kTumSX59lp72kD6GdYLufn3nXAD1PA4E/edit?gid=1604073602#gid=1604073602) as starting point. May need to talk with David Roberts if there are questions about data mapping doc or COBRS specific questions.
- [ ] Determine if LEAR db supports all the data from COBRS db extract
- [ ] Cut tickets as required based off of analysis done in this ticket.
Potential tickets may include:
* Update COBRS db extract script to pull missing data
* Update LEAR db and/or code to support data being pulled over from COBRS db extract

Start with the linked COBRS-to-LEAR data-mapping spreadsheet and compare its fields with the COBRS extracts and LEAR database structures. Done means documenting missing or unsupported data and creating focused follow-up tickets for extract, database, or code changes, consulting David Roberts where the mapping is unclear.
