ENH: Adding python sample for ConvolveImageWithKernel

No description provided.

Per discussion, could you please add 1) output with itk.imwrite for baseline comparison against the C++ example, and 2) perhaps a screenshot of matplotlib output?

[PranjalSahu]

Added matplotlib visualization screenshot.

I will build it locally to see how it renders.

Hi @PranjalSahu , Could you please rebase on master -- there were package improvements unrelated to your patch that may be causing issues in CI.

It is failing due to automatically generated test for baseline comparison between C++ and Python

Ah right, I've also run into issues with C++/Python baseline comparisons before. The ITKSphinxExamples macros were set up with the assumption that C++ and Python script output should always be the same and therefore use the same baseline image; as you've demonstrated here, there are exceptions to this rule.

Some possible paths forward:

1. Explicitly port the C++ sample to Python, using the exact same data and image pipeline, so that the result is the same
2. Disable the baseline comparison for now
3. Move the Python sample to a new example with a PYTHON_ONLY baseline check
4. Modify the CMake baseline macro so that different baselines can be explicitly provided for C++ and Python examples at the user's discretion
