Introduced import handler to handle with HLCD imports from the hydraulic boundary database property panel: WTI-1927- Added empty handler class to be substituted in the RingtoetsPlugin to prevent ArgumentNullExceptions on runtime.
Incorporated comments PO: WTI-1925- Changed default values for the HLCD information when there's no ScenarioInformation present in order to make it more insightful that default values are used.
