TST: Python 3.13

[pllim]

Would be nice to test against Python 3.13.

With python 3.13, installation via conda fails to place an executable in the path.

conda create -n glue-env -c conda-forge python
conda activate glue-env
conda install -c conda-forge glueviz
which glue
# no output

Following the newly updated conda installation instructions, glueviz grabs python 3.12.7 and everything works fine.

[tvwenger]

With python 3.13, installation via pip works, but throws a DeprecationWarning:

conda create -n glue-env -c conda-forge python
conda activate glue-env
pip install glueviz[all,qt]
# WARNING: glueviz 1.4.0 does not provide the extra 'all'
python --version
# Python 3.13.0
glue

Warning:

/home/twenger/miniconda3/envs/glue-env/bin/glue:8: 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.
