Return annual liquid precipitation depth as a Ladybug Data Collection.

        The amount of liquid precipitation (mm) observed at the indicated time for the
        period indicated in the liquid precipitation quantity field. If this value is
        not missing, then it is used and overrides the "precipitation" flag as rainfall.
        Conversely, if the precipitation flag shows rain and this field is missing or
        zero, it is set to 1.5 (mm).
