Add support for Python 3.13

[gdementen]

Currently all our dependencies have conda packages for Python 3.13 except for xlwings. Installing larray, larray_eurostat and larray-editor manually worked nicely (except exporting a selection to Excel, obviously). There is only a deprecation warning, which I have no idea where it comes from. We probably need to check where we parse dates. Might be in one of our dependencies though.

<string>:1: DeprecationWarning: Parsing dates involving a day of month without a year specified is ambiguious
and fails to parse leap day. The default behavior will change in Python 3.15
to either always raise an exception or to use a different default year (TBD).
To avoid trouble, add a specific year to the input & format.

Tentatively adding to 0.35 milestone. Will depend if I make the release faster than xlwings 😉

As of today (12 march 2025), xlwings is still not available for Python 3.13

xlwings 0.32.1 is now available

The warning is due to ipykernel. A fix is implemented in their git repository (ipython/ipykernel@b47db6f) but it was committed just after (on the same day) the latest stable release was released (6.29.5 on 2024-07-01). This should be resolved once ipykernel 7.0 is released (or maybe 6.5).
