### Rationale for this change Being able to run pyarrow without requiring numpy. ### What changes are included in this PR? If numpy is not present we are able to import pyarrow and run functionality. A new CI job has been created to run some basic tests without numpy. ### Are these changes tested? Yes via CI. ### Are there any user-facing changes? Yes, NumPy can be removed from the user installation and pyarrow functionality still works * GitHub Issue: #25118 Lead-authored-by: Raúl Cumplido <raulcumplido@gmail.com> Co-authored-by: Joris Van den Bossche <jorisvandenbossche@gmail.com> Co-authored-by: Antoine Pitrou <pitrou@free.fr> Signed-off-by: Antoine Pitrou <antoine@python.org>
