🚧 [Experimental] Get chart data

Runs a saved Wizard, QL, or Editor chart with the supplied parameters and returns flat tables. Pivot tables are not supported. Editor charts require Editor.setRawData(). Large integers in Wizard results may lose precision. Limits across all results: 100000 rows, 100000 cells, 1000 tables and 100000 schema columns; up to 800 columns per table. Exceeding a limit returns HTTP 422; results are not truncated.
