Ann ids are not unique when converting to the COCO format

[Robotatron]

Describe the Bug:
When using datasetinsights to convert the dataset for instance segmentation to the COCO format, the annotation IDs generated in the COCO are not unique. Frameworks such as Detectron2 will refuse to train because of this.

How to Reproduce?
Using datasetinsights to convert the dataset for instance segmentation to the COCO format

What did you expect to happen:
All annotation IDs are unique

Console logs / stack traces

Screenshots

Anything else you would like to add:
Generated several datasets with Unity Perception to confirm. Every generated dataset converted with datasetinsights had duplicate ann ids.

Environment:

• OS + version: Debian 10
• datasetinsights version: The latest commit with Instance Segmentation Support - bf6f824
