Claims data model updates

[sarah-tuva]

Describe your changes

• Updated the connector to output the latest version of the Tuva Claims Data Model
• Added logic to convert eligibility data on the member month grain to enrollment date spans using row number, lag, and Medicare/Dual Status to account for continuous enrollment and gaps in coverage.

Testing

Tested in Snowflake with Medicare LDS SAF data. Output can be queried in the following tables.

select * from medicare_lds_saf.tuva_claims_input.eligibility
order by patient_id, enrollment_start_date, enrollment_end_date
limit 50;

select * from medicare_lds_saf.tuva_claims_input.medical_claim limit 50;
