[Bug] Pip install fails

Hi,

With a conda environment with python 3.9 and itk 5.3.0 installing through pip fails. Specifically, this error gets thrown:
```
ERROR: Could not find a version that satisfies the requirement itk-ioomezarrngff (from versions: none)ERROR: No matching distribution found for itk-ioomezarrngff
```

When trying to install from source it gives:
```
× python setup.py egg_info did not run successfully.
