Simulation of Urban Mobility (SUMO)

The major changes are listed below and the full list of changes is given at https://sumo.dlr.de/Changelog

## Bugfixes

- sumo
  - Fixed crash in sublane simulation with unusual turning lanes (regression in 1.27.0)
  - Fixed invalid strategic lane choice when connections have reduced permissions
  - Fixed extreme reduction in simulation speed when setting high road speed limits in a dense road network
  - Fixed bugs where behavior diverges after loading state
  - Vehicles with departLane "best" or "best_prob" are no longer inserted on forbidden edges

- netedit
  - Fixed crash after renaming tlLogic (regression in 1.27.0)
  - Fixed crash after calling undo and 'select parents'
  - Fixed awkward workflow for reducing the network based on edge attributes.

- sumo-gui
  - Fixed invalid color for shown route when activating vehicle id background color (meso only) (regression in 1.11.0)
  - meso vehicles no do not flicker while waiting in a queue (regression in 1.27.0)
  - meso vehicles do not overlap while queued on a single lane (regression in 1.27.0)
  - fixed crash in meso (regression in 1.27.0)

- meso
  - The default of option --no-internal-links was changed back to 'true' when running with --mesosim. Short segments break jam propagation and this frequently happens with short internal links. (regression in 1.27.0)
  - fixed unsafe rail insertion

- duarouter
  - Fixed crash when called with --repair (regression in 1.24.0)

- TraCI
  - Fixed reversed driving after calling moveTo on a vehicle that is overtaking through the opposite direction

- tools
  - routeSampler.py: can now load marouter output (routeDistributions)
  - gtfspt.py: several fixes concerning stop placement on partial routes

## Enhancements

- sumo
  - CarFollowModel "Rail', can now include train resistance due to curvature by setting
  - CarFollowingModels now save their state (VehicleVariables)

## Miscellaneous

 - Fixed code signing issues for libsumo on macOS
 - Added new Railway scenario tutorial
