Bug#1044077: esda: FTBFS with pandas 2.0

[Rebecca N. Palmer]

Package: src:esda
Version: 2.4.3-4
Control: block 1043240 by -1

esda fails to build with pandas 2.0, currently in experimental.

Build log:
https://launchpadlibrarian.net/680699664/buildlog_ubuntu-mantic-amd64.esda_2.4.3-4_BUILDING.txt.gz

A common source of failures is that pandas.util.testing has been renamed 
to pandas.testing.  Both names were available in all 1.x versions (and 
hence in Debian stable and oldstable), so Debian packages that were 
using this can immediately switch unconditionally.
