Drt speed up

[tschlenther]

• Read all the necessary inforation from the drt input shape file (--drt-area). (The corresponding file needs to be updated in SVN!)
• remove command line options --drt-modes and --drt-case
• clean code
• set up with drt-speed up technically works. In first and last iteration, drt is simulated, not teleported.
• configuration still is in the code

ToDos (for separate PR):

• ToDo: make the ASC and the other speedUp parameters accessible from outside (i.e. from config or command line), again.
• ToDo: potentially get rid of the configuration in the code, generally!?
  --> this will simplify the caliration process by large means

@GregorRyb you branched/started from the main branch. I am not sure whether this should be merged back into there or into some other branch.

Also ToDo:

The DrtCaseSetup generates and saves drt input files next to the input config. This means, those files are overriden for each new run that is started. Really bad, in case we change something for one of the runs but not for all, for example the #vehciles for one of the areas.
