v2.0.0

Introduces classes for values that are returned from the Parser, and can optionally be used to provide values to the Serializer.

Upgrading from v1.x.x

The new classes returned from the Parser retain compatibility with existing code that expects [value, parameters] array tuples or stdClass objects, but the return type of Parser methods has changed so code using array typehints for values obtained from the Parser will need to be updated.
