Users can fit multiple 2D Gaussian components to the selected file with the image fitting widget. Frontend sends FITTING_REQUEST with file_id, region_id, initial_values, and other settings. Backend fits the current channel and polarization of the file. For each fitting iteration, backend sends back FITTING_PROGRESS to update the progress.
