Update calls to clp_area_penalties where deprecated func is called

The deprecated equal_area_penalties would be called in lieu of the new clp_area_penalties function

The pyglotaran-examples have in their model still equal_area_penalties which is correctly swapped with clp_area_penalties but them model.equal_area_penalties  was still called in some places instead of model.clp_area_penalties
