Bug report in GrandPotential dataframe and get_kinks

Hallo,

I have to report that when using the Grand Potential data frame the behavior is opposite of what it is on the webpage “pymatgen.analysis.interface_reactions module — pymatgen 2022.7.25 documentation”. The behavior of reaction energy in eV/atom is different from kJ/mol. I have attached the csv file for a reaction.
