Get relevant playstyle features for a team going in to a match

[erikbohne]

Is your feature request related to a problem? Please describe.
As a part of the prediction model, I want to be able to input ceratin parameters describing the playstyle of a team. This could be an important feature to include to the model as a weak defensive team against a strong offensive team has greater chance of score more goals etc.

Describe the solution you'd like
Not really sure how I want to implement this. But I have some ideas:

1. An independent model calculating playstyle outputs like "goals_for", "goals_against" etc that is a number from -1 to 1 representing the playstyle disadvantage/advantage for a team.
2. Values are direct inputs to the main model
