3. TEST: Add test baseline for shape2D …

   Add testing of shape 2D, using all 5 radiomics testcases. As shape2D only works with single slice segmentations, add new largest slice segmentations for each test case, and update code to allow adding of a "_2D" suffix to the testcase, indicating this 2D label should be returned as mask.
   
   Additionally update the getTestCase function to raise an error instead of returning None in case the test case could not be obtained.
