Why is Player a frozen dataclass and Team not?

[DriesDeprest]

For one of my projects, I'm interested in overwriting the team_id and player_id attributes of the Team and Player objects respectively in my TrackingDataset object. I want to replace the provider ID's with ID values from another provider.

I noticed that it can be done for the Team object but not for the Player object, as the Player class is a dataclass with the frozen parameter set to True (see: https://github.com/PySport/kloppy/blob/master/kloppy/domain/models/common.py#L116).

@koenvo why do we have set the frozen parameter set to True for the Player class? And why is it different from the Team class?
