CMS example with ServiceX 3 client

[ponyisi]

This works with uproot-raw right now with servicex==3.0.0b1. The func_adl version does not yet work (@gordonwatts is working on this), and in the end we would want a version with the final 3.0.0 release.

I've pushed the fixes for the func_adl version of the CMS notebook, with fixes courtesy of @gordonwatts (this needs func_adl >= 3.3.3).

I would like to update the ATLAS example as well, but it seems that at the moment there are problems with the UNL storage which prevent me from accessing those files.

I have updated the ATLAS examples.

The issue with the CI complaining about unrelated files should be fixable by rebasing to incorporate #226.

In the CMS ttbar notebook after the ServiceX delivery cell I see

Method Zip not found on object <class 'types.dict_dataclass'>

What is this about?

Other than the small things about imports above, could we please keep ServiceX off by default with USE_SERVICEX = FALSE to make the notebook work by default with the least amount of dependencies?

One more very picky request: could we please move USE_SERVICEX_DOWNLOAD into utils/config.py (probably into the global section) in an attempt to limit the amount of things to be configured in the notebook directly?

This is a particular issue related to how func_adl interprets the query, I know @gordonwatts is looking into it.

This looks all good to me, thank you very much! I believe @oshadura wanted to ensure we can run this on the Open Data coffea-casa before merging but I'll let her comment.

It works on https://coffea-opendata.casa with new ServiceX! thanks for the patience! :)
