The previous version of the table schemas was based on the until-then agreed data model in ADR-54. Since then things have changed: SWs have a spectral_window_id instead of a name, beam IDs are strings, and phase directions have a reference time and frame.
While some of these changes don't strictly need to be reflected on these schemas, it's better that we align with the ADR-54 data model to prevent confusions. Hence, we are renaming name -> spectral_window_id in the SW table and renaming time_origin -> reference_time in the Field table. The other changes are needed.
