Very small change to replace deprecated pandas df.applymap method with df.map. The map method was added in pandas 2.1.0, so this min version is added to the requirements and ci environments. I guess this min version should also be added to the conda-forge feedstock recipe, but I'll leave that to one of the maintainers.
