Add missing attributes for python package

• Added missing attributes for python package

ENDRELEASENOTES

The package attributes from the import system were missing since the edm4hep is rebound to the edm4hep submodule created with ROOT/cppyy. Similarly __version__ was set in the __init__.py but then lost

Having missing attributes shouldn't be a problem as we didn't experience it yet. But I think there was an intention to have edm4hep.__version__ available

Do we have to do a similar thing to podio?

Do we have to do a similar thing to podio?

No, podio is fine. In podio we use in wrappers or bring elements from the cppyy created module to the __init__.py.

Here we instruct the system to put under the name edm4hep the cppyy created module (normaly would be called edm4hep.edm4hep) instead of the edm4hep module from edm4hep/__inity__.py

EDM4hep/python/edm4hep/__init__.py

Line 31 in d7a209f

sys.modules['edm4hep'] = edm4hep

These will obviously be different after installation, but I don't see an easy way to check them without doing an install first. Anyhow, there is no reason to expect this to not work after installation, unless I am missing something?

I didn't think about it. I think it should be possible to find package without importing it and then check if the attributes' values are the same on the imported module. That should work for testing both in build environment and after install

But I don't expect that there should be any issues after installation
