Add counter attack parsing in StatsBomb deserializer

[DriesDeprest]

I would like to recognize the "From Counter" play pattern in our StatsBomb deserializer and thus add CounterAttackQualifier s to events with this play pattern.

I'm not sure what would be an elegant way to implement this.

I could create a function _get_counter_attack_qualifiers(event_dict: Dict) -> List[CounterAttackQualifier] which recognizes the "From Counter" play pattern. And then add this function in all the _create_events() methods of the different event type classes. But it feels a bit repetitive to add it to almost all of these event classes - @probberechts thoughts?

Ah yes, that would indeed be repetitive.

You could add the qualifier after parsing the events:

    def deserialize(self, event_factory: EventFactory) -> List[Event]:
        """Deserialize the event.
        """
        generic_event_kwargs = self._parse_generic_kwargs()
        events = (
            self._create_aerial_won_event(
                event_factory, **generic_event_kwargs
            )
            + self._create_events(event_factory, **generic_event_kwargs)
            + self._create_ball_out_event(
                event_factory, **generic_event_kwargs
            )
        )
        for event in events:
            # add possession qualfiers
        return events
