t: the temperature (K)- p: the pressure (Pa)
phase: is either "water", "ice" or "mixed". When it is not specified the "water" phase is used.
The result is the saturation mixing ratio in kg/kg units. On error nil is returned. The computation is implemented via the following function calls:
ws = mixing_ratio(p, saturation_vapour_pressure(t, phase))
