Support multi-column groupby in QueryBuilder #1909

Open DrNickClarke opened 1 month ago

DrNickClarke commented 1 month ago

groupby currently accepts a single column.

It would be useful if it could accept a list of columns, like Pandas and Polars.

This would be hash-based grouping.

The results should match Pandas for tests.
