[feature] support datasets with data defined on faces in mesh calculator, fix #30219, fix #30170
added "driver" and "group name" to the calculator interface.
MDAL now supports 3 drivers for storing results, so user must be able to choose appropriate driver and dataset group name (some drivers store multiple groups to 1 file)
