COMP: Copy-paste error

CID 1080810 The copied code will not have its intended effect.
In itkEuler3DTransformTest(int, char **): A copied piece of code is
inconsistent with the original

"e" in "e" looks like a copy-paste error. Should it say "par1"
instead?

COMP: Ensure FindDCMTK module works with and without DCMTKConfig.cmake file

In the case the provided DCMTK build or install tree doesn't have a
DCMTKConfig.cmake file, the first call to "find_package" should fail
quietly so that it doesn't prevent the rest of discovery process from working
as expected.

COMP: Big parameter passed by value

CID 1106765 Big parameter passed by value
Copying large values is inefficient, consider passing by reference;
size thresholds for detection can be adjusted.
In itk::​ImageBase<5u>::​SetDirection(itk::​Matrix<double, 5u, 5u>): A
large function call parameter or exception catch statement is passed
by value

NOTEs: ImageAdaptor also needed the change since it derives from ImageBase.
For consistency, ImportImageFilter was also changed.

Other Set methods in ImageBase already passed their rguments by reference.
