Bug#1053748: satpy: autopkgtest needs update for python-xarray 2023.09.0

[Graham Inggs]

Source: satpy
Version: 0.43.0-5
User: debian-ci at lists.debian.org
Usertags: needs-update

Hi Maintainer

Since the upload of python-xarray 2023.09.0-1, the autopkgtests of
satpy are failing [1].  I've copied what I hope is the relevant part
of the log below.

Regards
Graham
