Can't parse certain AIS message.

Hello.

"!AIVDM,2,1,6,A,56T6Bb82;pLA<t;N20Lht84j0qD8U8622222216:@@<55QW0=Rl45Dp888,0*48"

<- I can decode this strings with online AIS decoder well, but when I put it in your library, it returns null.

            try
            {
                var aisMessage = parser.Parse(test_string);
                //Console.WriteLine("MMSI Number : " + aisMessage.Mmsi); //Error. Mmsi is null.
                //Console.WriteLine("MMSI Number : " + aisMessage.mmsi); //Error. there is no member mmsi.
                //Console.WriteLine("Ship Name : " + aisMessage.ShipName); //Error. no member. "ShipName" even though web AIS parser get ship name on this string.
                //Console.WriteLine(aisMessage); //Print blank Texts.
                //Console.WriteLine("ShipType : " + aisMessage.ShipType); //no member. "ShipType"
                Console.WriteLine("Latitude : " + aisMessage.Latitude); //no member. "Latitude"
            }
            catch (Exception e)
            {
                Console.WriteLine("Error with this string : " + test_string);
                Console.WriteLine("Error code : " + e);
                Console.WriteLine("Stack Trace : " + e.StackTrace); 
            }

            loopratehz = 20.0f;
            return true;
        }

        public override bool Exit()
        {
            return true;
        }

    }
}

this code is mission planner plugin.

you can test this by install mission planner and put this *.cs file to plugins folder.

I can decode almost all message, but sometimes static and voyage related data? message doesn't read well.

When I reviewed the text example, I came across the following link:

https://github.com/yellowfeather/AisParser/blob/master/test/AisParserTests/MessagesTests/StaticAndVoyageRelatedDataMessageTests.cs

Although it may appear empty, the information is actually stored and utilized when the remaining part of the message is received. Therefore, there is no loss of data in this case, I guess

but I'm not sure it is true.
