Compile errors when instantiating OpenCLVector<T>

[N-Dekker]

An attempt to instantiate OpenCLVector<T> for a specific template argument T triggers compile errors. For example:

// Template instantiation for T = float.
template class itk::OpenCLVector<float>;

VS2022 output:

ITKimprovements\itkOpenCLVector.hxx(100,42): error C2039: 'map': is not a member of 'itk::OpenCLVector<float>'
ITKimprovements\itkOpenCLVector.hxx(137,43): error C2039: 'GetLength': is not a member of 'itk::Vector<float,3>'

Affected lines of code:

elastix/Common/OpenCL/ITKimprovements/itkOpenCLVector.hxx

Line 100 in 0852e7a

const_cast<OpenCLVector<T> *>(this)->map();

elastix/Common/OpenCL/ITKimprovements/itkOpenCLVector.hxx

Line 137 in 0852e7a

this->Write(data.GetDataPointer(), data.GetLength(), offset);

I guess these errors can be fixed easily. But are the affected member functions operator[] and Write) really necessary? Or can they simply be removed?

@dpshamonin Denis, do you still remember...?
