Support pandas 3.0 #1768
Description
The update to pandas 3.0 breaks the unittests and examples. See: #1767
From a quick glance I see some results of asserts change only very slightly and fail (e.g. less trailing zeros for Timestamps "2013-04-29T22:00:00.000000" instead of "2013-04-29T22:00:00.000000000"). I don't think that should be causing problems for users.
However, there are also appear to be some stricter type checks in pandas 3.0 causing quite some failures, which might cause problems for users as well.
