Deleting the Plaso Log File

[JakePeralta7]

First of all, thanks for this great project.

I’m currently using the plaso_ts recipe, and I’ve noticed that the Plaso log file is left behind in /tmp once the run completes.
While I can certainly grep out its path and delete it in an external script, it would be great to have an opt‑in flag for the TimesketchExporter — for example, something like --cleanup-temp — that automatically removes the temporary Plaso file when the export finishes.

Would you consider adding this as a configurable parameter?
