v0.1.5

• Support for PostgreSQL! The test suite now runs against PostgreSQL, and datools.explanations.diff now allows you to ask "why" about data stored in Postgres. Get excited!
• datools.sqlalchemy_utils.grouping_sets_query will now generate a GROUPING SETs query for databases that support grouping sets (e.g., Postgres, DuckDB) or the equivalent UNION ALL version for databases without grouping sets support (e.g., SQLite). For more, check out the example in the docs.
