ENH: Improve itk::DCMTKSeriesFileNames class coverage

Improve `itk::DCMTKSeriesFileNames` class coverage:
- Exercise the basic object methods using the
  `ITK_EXERCISE_BASIC_OBJECT_METHODS` macro.
- Use the `ITK_TRY_EXPECT_NO_EXCEPTION` macro when updating the filters.
- Exercise the Set/Get methods using the `ITK_TEST_SET_GET_VALUE` macro.
- Add arguments to the test to improve the class testing of the additional
  ivars.
