Modelling of swerving in the lane

In the proposal workshop on 8th of November 2022 for the next OSC project there was a request to be able to model a vehicle swerving in the lane. This is also a test requirement in the ALKS regulation (page 60):

4.1. Lane Keeping
4.1.1. The test shall demonstrate that the ALKS does not leave its lane and maintains
a stable position inside its ego lane across the speed range and different curvatures within its system boundaries. 4.1.2. The test shall be executed at least:
(a) With a minimum test duration of 5 minutes;
(b) With a passenger car target as well as a PTW target as the lead vehicle / other vehicle;
(c) With a lead vehicle swerving in the lane; and
(d) With another vehicle driving close beside in the adjacent lane.

Lateral actions currently only enable for single offset changes, but modelling consecutive lane offset changes is still quite cumbersome. You would have to concatenate multiple lateral actions like it is done e.g. here
