VtkAccessor

vtkXArrayCFReader

Reads data from a file using the XArray readers and then connects the XArray data to the vtkNetCDFCFREader (using zero-copy when possible). At the moment, data is copied for coordinates (because they are converted to double in the reader) and for certain data that is subset either in XArray or in VTK. Lazy loading in XArray is respected, that is data is accessed only when it is needed. Time is passed to VTK either as an int64 for datetime64 or timedelta64, or as a double (using cftime.toordinal) for cftime.
