Modify water column pressure using a scalar factor \lambda

We assume that the "melange back pressure" P_m = \lambda (P_i - P_o), where P_i is the vertically-integrated cryostatic pressure of an ice column and, similarly, P_o is the vertically-integrated pressure of a water column and \lambda \in [0, 1].

Then the modified integrated water column pressure is

P_o^{*} = P_o + P_m.

Reimplemented from pism::ocean::OceanModel.
