With pandas 2.3 (currently in experimental, but I'd like to upload it
to unstable soon), tqdm FTBFS because it has fail-on-warning tests:
https://launchpadlibrarian.net/815545434/buildlog_ubuntu-questing-amd64.tqdm_4.67.1-5_BUILDING.txt.gz

The warning in question (that apply() is going to stop including the
group-key column(s)) appears unrelated to tqdm adding a progress bar,
so the obvious solution is to ignore it:
