Add np.linalg.norm implementation

[arjavtrivedi]

Ready for review:

• Closes Missing np.linalg.norm implementation #1250
• Executed pre-commit run --all-files with no errors
• The change is fully covered by automated unit tests
• Documented in docs/ as appropriate
• Added an entry to the CHANGES file

Doc entry in docs/numpy.ipynb already covered by print statement here:

from pint.numpy_func import HANDLED_FUNCTIONS
print(sorted(list(HANDLED_FUNCTIONS)))

looks good to me, but someone with the permissions would have to rerun the tests so we can investigate the failures (the logs have expired since then).

I've managed to come back to this PR after quite a while. As such, I've updated the PR by merging upstream changes and addressed the previous feedback. The actions on the forked repository (here) appear to be passing, but I'm otherwise not sure why the PR workflows here are failing.

We are using Pint and np.linalg.norm a lot in our calculations and had to write helper a function to use it properly. Looking really forward to when this is merged! :-)

@arjavtrivedi (or @hgrecco / @jules-ch), could you merge in master? That should get RTD to build, and we'd need a maintainer to once again approve the workflow runs. Once tests pass I think this should be ready.

Cheers - unfortunately I don't have write access else I'd merge!

[hgrecco]

Thanks @arjavtrivedi !!

[arjavtrivedi]

Thank you @hgrecco for the great software!

This is not important anymore since the PR was merged (but I guess is good to know for any future PRs). Still, what I meant was to merge master into this branch (arjavtrivedi:feature/np-linalg-norm) to make use of some changes in master that fixed RTD.

[hgrecco]

@keewis I think that the current master has everything ok, right?

[keewis]

yep, it was just that on this PR RTD failed because the configuration still contained the system_packages: true line
