What would you like to happen?

Currently, python dataclasses are decoded by passing their encoded fields by position. This behavior does not work for dataclasses that are defined with kw_only=True (or has any kw_only fields).
Additionally, all dataclass fields are encoded and passed to the dataclass constructor, where only fields marked with init=True are accepted by the __init__ method of the dataclass.

Encoding the dataclass fields together with their field names and passing them by-keyword to the __init__ function should make handling of these type of dataclasses possible.
Encoding only the fields with init=True should make it possible to support dataclasses with init=False fields.
