Get only one property from the properties

I disagree because structures are exactly by the protocol docs. I'm working with some ideas how to improve use case of them. In one project I added to structure classes __toString magic method and Bolt library is automatically returning each structure as string. And for more structured like Node or Relationship I used JSON.

// -- PackStream/v1/Unpacker.php
$output = $this->unpackSpecificStructure($result, ...$this->structuresLt[$marker]);
if ($result && $output instanceof \Bolt\structures\IStructure)
    return (string)$output;

Also structures are currently without version. It should be part of PackStream/v1. Usually I'm saying to myself, if authors of Neo4j will create new version PackStream, it will be more clear how to implement the structures.

I don't like the idea if somebody has to use third-party classes (ex. Bolt) as main use case. I mean, if I call Bolt to execute query, I don't want to receive some Bolt\structures<Cls>, because it can change to versioned PackStream or new version of PackStream, it can be problematic in future.
