【功能需求】加载数据集标注时提供进度展示

[lartpang]

因为我使用的功能涉及到了Mask，实际相关代码在这里：

X-AnyLabeling/anylabeling/views/labeling/label_widget.py

Lines 3571 to 3586 in 102bc9f

	for image_filename in image_file_list:
	if image_filename.endswith(".json"):
	continue
	label_filename = osp.splitext(image_filename)[0] + ".png"
	data_filename = osp.splitext(image_filename)[0] + ".json"
	if label_filename not in label_file_list:
	continue
	input_file = osp.join(label_dir_path, label_filename)
	output_file = osp.join(output_dir_path, data_filename)
	image_file = osp.join(image_dir_path, image_filename)
	converter.mask_to_custom(
	input_file=input_file,
	output_file=output_file,
	image_file=image_file,
	mapping_table=mapping_table,
	)

由于Mask读取较慢，大量数据导入时这里会阻塞界面，或许提供一个进度条会更好？
