[Debian-med-packaging] Bug#1001349: python-anndata: autopkgtest fail with pandas 1.3: missing openpyxl

[Rebecca N. Palmer]

Package: python3-anndata
Version: 0.7.5+ds-3
Severity: serious
Tags: patch

pandas.read_excel() now defaults to using openpyxl only, not 
openpyxl-or-xlrd:

Please update your build and test dependencies.

(This didn't show up in my local test run because I did that in 
unstable, where #1001020 appears first.)
