The `PETDICOMExtension` is failing in nightly with this error

Obviously it is using an old pydicom module

It appears you are using an old nightly (28653). Use the current nightly (28668) and reinstall the extension using the extension manager.

This specific issue was solved 7 days ago in [https://github.com/QIICR/Slicer-PETDICOMExtension/commit/f715f85b06d79ec4d254253cfb9cfc046b2ee804](https://github.com/QIICR/Slicer-PETDICOMExtension/commit/f715f85b06d79ec4d254253cfb9cfc046b2ee804). Everything appears to have been solved as the current nightly tests are not showing this failure.
