import multiple segmentations from coco format json

[Ljung323]

Problem

when converting coco annotation to label studio format, only the first item is used as a segmentation.

label-studio-sdk/src/label_studio_sdk/converter/imports/coco.py

Line 54 in 5fceb54

segmentation = annotation["segmentation"][0]

for example

expected

actual

Suggestion

can we use all segmentations instead?
or am I misunderstanding something?

from

label-studio-sdk/src/label_studio_sdk/converter/imports/coco.py

Lines 218 to 227 in 5fceb54

	if "segmentation" in annotation and len(annotation["segmentation"]):
	item = create_segmentation(
	annotation,
	categories,
	segmentation_from_name,
	image_height,
	image_width,
	to_name,
	)
	task[out_type][0]["result"].append(item)

to

something like this

        if "segmentation" in annotation and len(annotation["segmentation"]):
            for single_segmentation in annotation["segmentation"]:
                item = create_segmentation(
                    annotation["category_id"],
                    single_segmentation,
                    categories,
                    segmentation_from_name,
                    image_height,
                    image_width,
                    to_name,
                )
                task[out_type][0]["result"].append(item)

It seems it's just not implemented. Could you submit a PR with this?
