Import error with new itk version 5.3.0

[mbrei]

Description

With the latest release of itk (version 5.3.0) the BinaryThinningImageFilter3D does not work anymore, and the import fails with an AttributeError.

Steps to reproduce

Package versions:

itk==5.3.0
itk-core==5.3.0
itk-filtering==5.3.0
itk-io==5.3.0
itk-numerics==5.3.0
itk-registration==5.3.0
itk-segmentation==5.3.0
itk-thickness3d==5.2.0

Minimal example:

import itk

PixelType = itk.ctype("unsigned char")
ImageType = itk.Image[PixelType, 3]
image = ImageType.New()

skeleton = itk.binary_thinning_image_filter3_d(image)

fails with the following error message:

Traceback (most recent call last):
    skeleton = itk.binary_thinning_image_filter3_d(image)
  File "/Users/mariebrei/opt/anaconda3/envs/test_env/lib/python3.9/site-packages/itk/support/lazy.py", line 138, in __getattribute__

    from . import _Thickness3DPython
AttributeError: PyCapsule_Import "_ITKCommonPython._C_API" is not valid

With itk==5.2.1.post1 everything works as expected.
