feat: Annotation and Measurements support on multi-frame DICOM (#2973)
* added utilities to get frameNumber from imageId and add frameNumber to per-frame instance copy * Fix measurements' display texts on the Measurements Panel to have the correct instance number and frame number * fixed minor React bugs (errors on console) * fixed React's console bugs that are logged for some series that doesn't have "description" * bug fix - multi-frame files was not loading frames correctly. It was loading Frame 1 twice, and not loading the last frame. Due to wrong frame number indexing (frame number begins with 1, not 0) * metadata parser fix - providing default values of imagePlaneModule * measurement SR support on multi-frame DICOM * bug fix - jumping to the selected measurment on multi-frame DICOM * upgrade dcmjs dependency to 2.8.1 * StudySummary component - allow "description" to be null * make getUIDsFromImageID() method public from MetadataProvider * imageId usage fixes to be more stable * change the variable name to be more meaningful * fix metaProvider importing * for(...of) instead of for(i=0;i<length;..) as that doesn't assume anything about the layout/design and just gets next until done. * use Array.findIndex instead of plain for loop * use ReferencedSOPSequence[0] - because the ReferencedSOPSequence is an array that happens to have attributes of child zero when of length 1, but you shouldn't count on that. * DisplaySetService.getDisplaySetForSOPInstanceUID() - added optional frameNumber parameter for future usage : now they are just ignored as we are not supporting multiframe splits * simple code refactoring * refactoring for checking undefined values - mappedAnnotations * remove unreachable code * code refactoring - prefer conditional chaining * fix how we access imageIds of viewport (StackViewport)
