Inconsistency between ITKImageProcessing vector images and DREAM3D vector images

ITKImageProcessing encodes RGB(A) and vector images in Dream3D data container differently whereas DREAM3D encodes them the same way.

In DREAM3D,
RGB(A) and vector images: QVector cDims(1, nb_components);

In ITKImageProcessing:
Vector images components: QVector cDims(nb_components, 1);
RGB images: QVector cDims(1, 3);

ITKImageProcessing uses this implementation difference to differentiate between RGB(A) images and vector images. A solution for ITKImageProcessing to differentiate between RGB(A) and vector images could be with additional input from the user (check box). This additional input would be selected at the filter level.

首先比较 issue 中 ITKImageProcessing 和 DREAM3D 的表示方式：RGB(A) 图像和向量图像的组件维度采用了不同的编码方式。明确预期的修复方案是一致的编码，还是过滤器级别的用户复选框，然后验证 RGB(A) 图像和向量图像在 Dream3D 数据容器中仍然可以区分。
