Upgrade pandas to version 3.0

[paolafer]

I would like to propose we update pandas to 3.0, since I often get warnings such as

whenever I try to add a column to a dataframe as df['new_column'] = something. To my understanding, this warning is, in most of the cases I have to deal with, unnecessary, but, still, to be on the safe side, I use insert, instead, which makes the code less readable.

According to the documentation, the problem causing the warning should disappear with version 3.0 of pandas.
Let me know what you think.
