Error with pandas `Dataframe`.`applymap` usage with latest `pandas=3.0.2`

[ppreshant]

I get this error when running rhea with the latest version of pandas (on the python_package_i8 branch)

      df_nodes_coverage[coverage_cols].applymap(lambda x: 1 if x < 1 else x)

      return object.__getattribute__(self, name)
             ~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^
  AttributeError: 'DataFrame' object has no attribute 'applymap'

Fix:

df_nodes_coverage[coverage_cols].applymap -> need to change to .map
