Control sleep between downloads

I would love to be able to manually control, via a flag, the delay between downloads, instead of the hardcoded value in e.g. https://github.com/rg3/youtube-dl/blob/244cd04237fe4a1e4d92421711f41de3c2566d5c/youtube_dl/extractor/pluralsight.py#L214:

                # Pluralsight tracks multiple sequential calls to ViewClip API and start
                # to return 429 HTTP errors after some time (see
                # https://github.com/rg3/youtube-dl/pull/6989). Moreover it may even lead
                # to account ban (see https://github.com/rg3/youtube-dl/issues/6842).
                # To somewhat reduce the probability of these consequences
                # we will sleep random amount of time before each call to ViewClip.
                self._sleep(
                    random.randint(2, 5), display_id,
                    '%(video_id)s: Waiting for %(timeout)s seconds to avoid throttling')

Why does the --sleep-interval not kick in when a file “has already been downloaded and merged”?

@dstftw That doesn’t seem to impact playlists. Once in a playlist download, only the internal sleep of randint(2,5) is in effect.
