Improve argument list parsing

[Agustin Alba Chicar]

Use getopt API for improving argument list parsing.

Also include lane smoothing as an optional.

We need to provide:

• Print lanes
• Print waypoints
• SDF models
• RNDF file
• Use interpolation or not
• Add a terrain, terrain option
• Debug mode

In the future we need to be able to add other input files. We can wrap some now but it will be good to have all this in a config file and pass it because it is simpler to use and keep. @andres_fortier , @JChoclin what do you think?

Looks good! As a suggestion I would have each functionality in a separate issue so you can tackle them in small chunks instead of one big, long-lasting issue.

There is no further develop required with this as we use now SDF for passing all the variables to our plugin.
