Hello.
Currently, I try to read fixext like a MessagePackObject, but it's not possible.

1. fixext read as Binary (MessagePackObject<byte[]>) instead MessagePackObject<MessagePackExtendedTypeObject>. Some extra proves I found here https://github.com/msgpack/msgpack-cli/wiki/New-message-pack-spec .
2. I can't convert to Bytes[] by AsBinary because you check string here:

An exception of type 'System.ArgumentException' occurred in MsgPack.dll but was not handled in user code: 'Do not convert System.Byte[] MessagePackObject to MsgPack.MessagePackString.'
   at MsgPack.MessagePackObject.VerifyUnderlyingType[T](MessagePackObject instance, String parameterName)

What should I do for reading objects from a stream and just check the object for fixext? (in my stream I also have other types)
