[Bug] ToolGroupSpecific configuration for changing segment color is changing color across other toolgroup

[jithenece]

Describe the Bug

• Changing color of a segment using segmentation representation of specific toolgroup also changes colors of segments of other toolgroup.
• Below seems to change color in segmentations of other tool groups too segmentation.config.color.setColorForSegmentIndex( toolGroupId1, segmentationRepresentationToolGroupId1[0], 1, [0, 0, 255, 255] );

Steps to Reproduce

1. Clone the cornerstone3D repo
2. Use the labelmapToolGroupSpecificConfiguration/index.ts to replace below file path packages/tools/examples/labelmapToolGroupSpecificConfiguration/index.ts
3. Run the example using yarn install yarn run example labelmapToolGroupSpecificConfiguration
4. Observe the page by commenting the promise statement in line number 334

The current behavior

• Modifying segment color of a segmentation representation of a one tool group should not modify other tool groups.
• Currently it seems to modify colors on the same toolgroup if we add sleep and other toolgroup without any sleep timer in the code

The expected behavior

• changing color config of a segment should not impact other segment of different segmentation representation of same or different toolgroup
• for the example on labelmapToolGroupSpecificConfiguration, the color should be blue for one of the inner circle. instead it seems to make blue on other inner circle.

Yes, it appears to be a problem. I believe the issue also occurs with the same toolgroup. For example, if you change the color of a segment in segmentation 1, it will also change in segmentation 2 within the same toolGroup. This is actually a more significant issue than the one you mentioned. Rest assured, I will address and resolve it.

By the way, I'm interested to know why you have two toolGroups. What is your specific use case?

Thanks @sedghi for checking on this.

I had 4 viewports. One viewport using CT to show only tumor segmentation. Other 3 viewport using PT/CT to show tumor and organ segmentations. Using a single toolgroup, it seems we cannot achieve this. so I had to create two different toolgroups for different viewport combinations. Please let me know if there are better ways to implement this.
