feat(SR): Support SCOORD3D point annotations and IDC bounding box annotations

[rodrigobasilio2022]

This PR adds the support for SCOORD3D point annotations and IDC bounding box annotations. It depends on OHIF PR OHIF/Viewers#3631, that enables modes to inject customizations in the dicom sr extension. It defines a function that will convert IDC SR annotations to OHIF/Cornerstone compatible ones.

For now, just POINT SCOORD3D annotations and IDC SR bounding boxes are supported, but other annotations will be included in near future. This PR handles SCOORD3D point annotations by projecting them to all images that are distant less than a threshold value, actually set to 0.1. It is important to note that one SCOORD3d can create multiple SCOORD annotations.

It defines a function that will convert IDC SR annotations to OHIF/Cornerstone compatible ones.

As a correction, there is nothing specific to IDC in the samples that were shared for the purposes of developing this functionality. Those SR samples that follow DICOM standard were prepared by IDC, but that's where connection with IDC ends. Those samples follow the standard, without introducing any tool- or project-specific conventions to be relied upon.

I think what you are trying to say in the above is that OHIF/Cornerstone has implementation-specific conventions/requirements, and cannot use standard DICOM SR annotations without applying some transformation to those first.
