Bookmark: Delete Traffic Module

Before we publish VirtualFluids we should make sure that all parts of the published code are still maintained. In this Issue, I would like to discuss the Traffic module. The module is located in src/gpu/Traffic and used by apps/gpu/LBM/TrafficTest. The traffic module is enable via the cmake flag BUILD_VF_TRAFFIC. This flag is checked in gpu.cmake line 84.

From my perspective, there we have two options:

1. Update the traffic module, add a regression test and enable the traffic module in our CI compile jobs. or
2. Remove all source code related to the traffic module from the repository. In this case we can keep this issues as a bookmark and link the commit containing the deletion here:
