Subject: [PATCH] Add gap parameter to image concatenate nodes

Introduces a 'gap' parameter to both image_concatenate.py and image_concatenate_multi.py, allowing users to specify spacing between concatenated images. Also updates the imitation_hue_node.py to process batches with progress bar support and corrects mask handling for multiple target images.
