ENH: Support any scalar type (not just real) as input pixel type

Allows the user to pass input images to ElastixRegistrationMethod and TransformixFilter whose pixel types differs from the internal pixel type. The elastix/transfomix library will now convert those images automatically, using `itk::CastImageFilter`: pull request SuperElastix/elastix#882 commit SuperElastix/elastix@58e0a7b "ENH: Convert the input images to the user-specified internal pixel type"
