Parallel

Current time : 18 minutes for a -a run. Requires some additionnal testing that should be carried next week
So you want me to break a logging design choice that was not made by me on a PR that's dedicated to parallelize PSUL ? If you want to send your logs to the moon, please make a PR adding a MoonHandler to the psullogger, and that will be done. two minutes tops. Now I kinda decided to focus more one the parallelization part rather than the logging. But please, go ahead and add a handler to send the logs to elasticsearch of whatever if you want to.
