Bug#1043240: transition: pandas 1.5 -> 2.0

[Rebecca N. Palmer]

Package: python3-pandas
Version: 1.5.3+dfsg-4
Severity: wishlist
Control: block -1 by 1043093

pandas 2.0 is now in experimental.  However (as you might expect from 
that version number), it breaks around 40 other packages, and it is 
hence likely to be some time before it moves to unstable.

Upstream release notes:
https://pandas.pydata.org/docs/whatsnew/v2.0.0.html#backwards-incompatible-api-changes

Build test results:
https://launchpad.net/~rebecca-palmer/+archive/ubuntu/pandas2p0/+packages

Autopkgtest results:
https://qa.debian.org/excuses.php?experimental=1&package=pandas

These packages have not been (fully) tested because they build- or 
test-depend on dask, which is already known to break (#1043093):
dask.distributed extra-data flox intake pint-xarray python-cooler 
python-geotiepoints python-streamz python-xarray sunpy xarray-safe-s1 
xarray-sentinel

These packages have not been build-tested because they do not exist in 
Ubuntu (probably because they were broken already, as none of them are 
in Debian testing either):
