Basic file I/O with Uproot -> Opening the file -> skhep_testdata module

[JacekHoleczek]

In the "Basic file I/O with Uproot" chapter, in the "Opening the file" section, you unconditionally "import skhep_testdata".
However, "standalone" users who installed the full "scikit-hep" will not have this module.
I'd like to propose to add in this place a small:
Note: you may need to run "conda/mamba/pip install scikit-hep-testdata" in order to have this module.
Or maybe simply:
import skhep_testdata # you may first need to run conda/mamba/pip install scikit-hep-testdata

scikit-hep-testdata

[JacekHoleczek]

Sorry, I was not clear enough.

I am trying to go through the tutorial as a "newcomer" would.
So, as someone who only installed either "uproot", or "scipy", or "sckit-hep".
I can't rely on one finding/consulting/applying the additional tutorial's requirements.txt file from git.

In general, I expect from Python that whenever one gets a "No module named 'AddOn'" error, one needs to "conda/mamba/pip install AddOn".
If that is not the case, I think it would be nice to add an explicit note in the tutorial that some magic "conda/mamba/pip install Module" provides the required "AddOn".

That's the case for "skhep_testdata" which needs "scikit-hep-testdata".
