Return annual Precipitable Water as a Ladybug Data Collection.

        This is the value for Precipitable Water in mm. (This is not rain - rain is
        inferred from the PresWeathObs field but a better result is from the Liquid
        Precipitation Depth field). It is not currently used in EnergyPlus calculations
        (primarily due to the unreliability of the reporting of this value). Missing
        value is 999.
