Commuter Testing should not be coupled with dynamic NPIs

[HenrZu]

Motivation / Current Behaviour

in the advance function of the secirvvs model, we always set

this->get_model().parameters.get_start_commuter_detection() = (ScalarType)t_start;
this->get_model().parameters.get_end_commuter_detection()   = (ScalarType)t_end;

Testing should not necessarily be coupled to the dynamic NPIs in this way. Also, we can't change the non detection value during the simulation.

Enhancement description

make the code more modular and split up features instead of combining them.
