This file contains utilities to load GANs datasets.
Similar to how COCO dataset is represented in Detectron2, a GANs dataset is represented
as a list of dicts, where each dict is in "standard dataset dict" format, which contains
raw data with fields such as:
- input_path (str): filename of input image
- fg_path (str): filename to the GT
