Hello, I’d like to use itk.CoocurrenceTextureFeaturesImageFilter using two different parameter settings, one after the other. However I’m failing to execute the proper commands to retrieve the image of the second configuration - i just get the same output as the first set. Here’s my function, which i call twice:

```auto
def cooc_filter(my_numpy_array, settings):
    itkImage = itk.GetImageFromArray(my_numpy_array)
    filtr = itk.CoocurrenceTextureFeaturesImageFilter.New(itkImage)
    <configure(settings)>
    filtr.Update()
    result = filtr.GetOutput()
    glcm_maps = itk.GetArrayFromImage(result)
    return glcm_maps

```

I’ve read about similar issues suggesting the use of result.DisconnectPipeline(), but this doesn’t seem to work. Any tips would be great.
