GSPS Writer Operators for Object Detection and Segmentation

[CPBridge]

Add operators to write out GSPS DICOM objects for:

• Object detection (bounding box)
• Segmentations (overlay boundaries)

We can leverage highdicom to do this

[CPBridge]

Note that we can largely re-use the example in the Nuance PIN example for the object detection writer, with a few tweaks to make it more general: https://github.com/Project-MONAI/monai-deploy-app-sdk/blob/main/platforms/nuance_pin/app/post_inference_ops.py
