Improve error reporting #341
Description
When reducing a large list of IDFs files, I got an error "AssertionError: Heating setpoint must be lower than the cooling setpoint" but have no way of telling which IDF file is causing this error. The last entry above the error was: "Reducing perimeter zones in <_io 0% | | 0/68
It would be nice if the flag reported which file caused the error.
