Bug#1055801: pandas: test failures with Python 3.12

[Rebecca N. Palmer]

Control: severity -1 normal
Control: retitle -1 pandas/pytables: ignored test fails with Python 3.12
Control: found -1 2.1.3+dfsg-1
Control: tags 1057805 pending

In 1.5.3+dfsg-8, these are ignored, so are no longer an FTBFS but are 
still a bug.  I don't know whether they're a pandas bug or a pytables 
bug; they don't appear to be known to either upstream.

(The build failure on armhf, #1057805, was because this xfail took 
precedence over the existing run=False xfail and hence exposed a 
long-known crash, #790925.  This should be fixed in -9.)

If the 'affects' is because you were trying to test those reverse 
dependencies in Python 3.12, this should now be possible.
