feat: Make CKF branching configurable from python

[andiwand]

Currently we hardcode the branching config in python which makes it hard to find the default and unchangeable for the user. With this PR I add a struct TrackFindingConfig which defines the branching params and lower the defaults in hope to spare some resources with ttbar events.
