refactor: truth tracking examples: fix ODD setup and make default

[AJPfleger]

Why?

• The ODD was never set correctly
• We usually want to run on the ODD and only have the generic for quick checks.

Note

I put the import from acts.examples.odd import getOpenDataDetector under main, since usually, we want to call the runTruthTrackingFITTERNAME() from outside.

Opinions definitely diverge on this.

One of the primary goals of the Python bindings was originally to get rid of all command line options in favor of a more robust configuration mechanism. I was trying to get the examples be actual examples, rather than flexible command line utilities, where you can open a file, read what it does, and use it.

But I see we've abandoned this approach for at least the ODD example again, where we have dozens of command line options, and therefore two configuration layers on top of each other.

I personally think we're going in the wrong direction here, but I won't try to change everyone's minds.

With the original design, you could have copied the file and called into runTruhTrackingXXX, to reuse common configuration.

IMO we could just change this to ODD and have no CLI. I don't see a benefit in switching between generic detector or ODD right now.

It could be a different story if we do physmon on different geometries. We should do that and it might be useful there. But usually one has to change the tracking chain (at least config of algs) to get decent performance and as long as we do not have a generic mechanism of reading a config from somewhere I would also be in favor of having different scripts instead of if all over the place.

[AJPfleger]

At least I use the generic detector quite frequently, because it is simpler and faster than the ODD, so I would like to keep it there.

How about the current suggestion? Makes it easily changeable in the python script, avoiding all command line options. And it fixes the ODD setup, that was broken before (the main reason, I made changes).

[title and description need to be change, no need to comment on those.]
