Default highWaterMark is now set properly when using stream Duplex's writableObjectMode and readableObjectMode options. Added condition to the already existing split objectMode test to ensure the highWaterMark is being set to the correct default value on both the ReadableState and WritableState for readableObjectMode and writableObjectMode.
