Group modal and orthographic projection improvements

[sashankaryal]

What changes are proposed in this pull request?

• Show pointcloud slice selector in group datasets (also resolves [FR] App should include point cloud slices in group selector when projection metadata is available #2722)
• Address a number of bugs in grouped datasets

Known issues

• Pinned slice persists in the looker when switching samples, but not in the sidebar. Not a regression.
  • It didn't use to persist in the looker as well, but that has been fixed.
• Orthographic projection metadata, if calculated, is only available in the pointcloud slice. However, the sidebar shows this field for all slices. This can create a confusing experience. Not a regression.
• Projected bounding boxes are painted off the center once in a blue moon-ly. I haven't been able to reproduce this but I'll dive deeper in next iteration. Not a regression.
• Nit: Group dataset primitives and state management need some rethinking and refactoring. Atoms and selectors are scattered across multiple places and it's usually not clear how different states are related, or when certain state updates take place.

Regression Testing

• Test with quickstart dataset.
• Test with quickstart-groups dataset.
  • Without calculating orthographic projection, for each slice, expand a sample and navigate prev/next. Change pinned sample and navigate prev/next.
  • Repeat above but calculate orthographic projection first.
