Update dependencies

[phackstock]

Pull request

This PR updates the following dependencies to the currently latest versions:

• scmdata
• pandas (to version 2)
• pyam-iamc
• pytest

the biggest change is pandas 2 which broke a number of tests. I have done my best to implement fixes related to deprecated pandas functionality. There's still currently a couple of tests failing on my machine. They are:

• test_load_rewritten_scen7 failing because there's two warnings instead of one

• test_writing_identical_rcpdat all the tests with add_extra_data = True are failing (fixed per 2af4eb1)

• test_default_config and test_readme seem to be failing because I don't have wine installed. I tried to install it but somehow my antivirus marks it as a virus and does not let me install it.

• [ ] Tests added

• [ ] Documentation added (where applicable)

• [ ] Example added (either to an existing notebook or as a new notebook, where applicable)

• [ ] Description in CHANGELOG.rst added

@znicholls or @lewisjared I checked Allow edits by maintainers in case you have time to take a look. Could be easier for you to fix the remaining failing tests.

Awesome. I've got to do some other work but I can then take a look at getting the CI running again and see where we end up...

Looks like we'll have to wave goodbye to python3.7 and 3.8 with this PR as scmdata 0.16.1 requires >=3.9.
