BUG: Fix keep-output command line argument in profiling script

[pschultzendorff]

Proposed changes

The argparse argument --keep_output in the profiler was initiated with action="store_true" and default=True. This meant it couldn't be set to False. I changed the argument to --clear_output with action="store_true", which is automatically initiated with default=False. Everything stays the same, except one can now actually use the flag.
