ENH: add PixelType = short restriction to Itk2DicomConverter::itkimag…

…e2dcmSegmentation Tempalted function Itk2DicomConverter::itkimage2dcmSegmentation should not be instantiated with PixelType other than short. This is because we do not handle any other pixel type for writing DICOM segmentation object. Any attempt to instantiate should result in a compile time error, warning the developer about the limitation.
