Make LuST compatible with SUMO 1.0.1

[kenog]

In order to use LuST with SUMO 1.0.1, the file names in <route-files>
and <additional-files> in *.sumocfg need to be separated by commas.

I also tested this patch with SUMO 0.32.0 and it works as well.

I really appreciate the fact that you spent the time to make this pull request, but we have a different issue going on here, and it is not the comma in the files.

The mobility models in sumo have changed over time, and when I tried to move it to sumo 0.27 we have found bugs and quirks in the traffic demand, so I had to roll back to 0.26. This scenario has been validated with sumo 0.26, and I don't have access to the validation data anymore. Even if we make it SUMO 1.1.0 compatible, it's not going to be validated.

In order to port it to the current version of sumo, the network must be re-converted, the TLS definitions must be updated, the realism of the vehicles' behavior has to be re-validated, the DUE mobilities have to be recomputed from scratch and finally, the outcome must be validated with the real data that I don't have anymore.

If you don't care about a validated mobility but you want to use all the latest features of sumo, I suggest you to try https://github.com/lcodeca/MoSTScenario.

Oh wow ok. I just noticed sumo complaining about not being able to read the route files and had a look at MoST. There I found the commas and since the sumo accepted the files after adding them, I naively assumed that this was it.
However, thank you very much for the detailed explanation. Fortunately were able to use SUMO 0.26 in our simulation with only minor adjustments.

No problem, I'm always happy to help!
