Returns extrapolated mS/cm conductivity.

    Args:
        temps ([float]): A sequence of temperatures. units: K
        diffusivities ([float]): A sequence of diffusivities (e.g.,
            from DiffusionAnalyzer.diffusivity). units: cm^2/s
        new_temp (float): desired temperature. units: K
        structure (structure): Structure used for the diffusivity calculation
        species (string/Specie): conducting species

    Returns:
        (float) Conductivity at extrapolated temp in mS/cm.
