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.

for example

expected

actual

Suggestion

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

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?
