Updates for the Tuva Project v0.3.0 release

Describe your changes

Resolves #10

Updated the Tuva Project package version and fixed a bug with the version range.
Simplified the yml config options.
Removed the full data override logic. This will be added back in a future PR when the S3 seed functionality is added.

Tested with dbt build, dbt build --select tag:tuva_claims_demo, and dbt build --exclude tag:tuva_claims_demo in Snowflake.
