Handle multiple inputs in obstacle detector exe

The obstacle detector executable can now handle different input
formats, chosen by a command line argument, automatically.

It also does not automatically exit after a certain amount of time.
For the demonstration purposes, this seems a much better choice,
than having to restart the executable every-so-often.
