Update documentation for citations and input file formats

[jkikstra]

Updates documentation:

• First commit: be more explicit about input data (not .xls, only .xlsx or .csv)
• Second commit: update citations to Nicholls et al. (2022) and Kikstra et al. (2022), and fix Zenodo links where necessary

Adresses #25

Looks like a test is failing because of a numpy update;

=========================== short test summary info ============================
FAILED tests/regression/test_workflow.py::test_workflow_ciceroscm - AssertionError: AttributeError("module 'numpy' has no attribute 'float'.
  `np.float` was a deprecated alias for the builtin `float`.

Looks like a test is failing because of a numpy update;

I guess there's two ways of fixing this, pinning the numpy version or changing np.float to float. I would say the latter is preferred.

Yes - just need to find where it is actually used, will try and go down the rabbit hole

If you, for now, pin the version at numpy <= 1.19 it should be fine (see the deprecation section of the numpy 1.20 release notes https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations).
Once cicero addresses the numpy issue you can remove the version pin.

OK.

Have made an issue on openscm-runner; openscm/openscm-runner#81

Thanks for the MR and diagnosis. If the current master branch of openscm-runner fixes the tests, I'll make a new release.

[jkikstra]

Okay - thanks @lewisjared!

Let me know when we can/should update the dependency, since it was so far pinned on 0.9.1.
Maybe in a separate PR?

[lewisjared]

Sorry I missed this. I just cut a new release so that should be available in the next hour

[lewisjared]

Hitting a few roadblocks regarding test coverage so it might not be resolved today, but I'll fix as soon as I can

openscm/openscm-runner#83

[phackstock]

Once the pin is removed and the tests run, good to merge from my side.

[jkikstra]

Adjusted, and passing tests now.

[phackstock]

Perfect, thanks @jkikstra
