Close NVidia Omniverse after terminating the dataset generation

[agalbachicar]

Desired behavior

Instead of keeping the NVidia Omniverse up, close the application once it finishes to gather all the data.

Alternatives considered

As it is right now, it is just keeps open. It may be better to simply close it. Alternatively, we could log and keep the application open.
Another option is to control it via a configuration entry.

Implementation suggestion

Log and terminate.
