Residual Helmholtz Energy for a generic Cubic Equation of State.
Calculates the residual Helmholtz Energy for a generic Cubic EoS as defined by Michelsen and Møllerup:
This routine assumes that the is not a constant parameter (as it uses to be in classical Cubic EoS) to be compatible with the three parameter EoS RKPR where is not a constant and has its own mixing rule.
