Multi-file import error

Hi! I have been trying to use this to import some ibw files, and have had good success for one file at a time, but as soon as I try to import more than one file using the multiple_files=True optional addition to open_file_dialogQT(), I get an error that the tuple object is not callable.

Output log and versions:

fnames, file_filter = func(parent, caption, file_path, filter=file_types, options=[QtCore.Qt.WindowStaysOnTopHint])

TypeError: 'tuple' object is not callable

I have fed it a few basic topography images (.ibw files) that worked when selecting a single file.

Start at sidpy/io/interface_utils.py, line 256, using the reported openfile_dialog_QT(multiple_files=True) call as the reproduction case. Compare that path with the working single-file call and verify that multi-file selection completes without the tuple-not-callable error while preserving single-file behavior.
