soundcloud soundscrape no longer working (401 unauthorized)

Hey, it seems to me like soundscraping soundcloud is no longer working. Following the issue throughout the code its seems that a 401 http error, unauthorized is the issue, which is the response received in line 526 [get_hard_track_url()].
Does this have something todo with the new security update from soundcloud? https://developers.soundcloud.com/blog/security-updates-api

would be super happy if a fix for this issue was found.

best wishes,
simon

Start in soundscrape.py at get_hard_track_url() around line 526 and follow the process_soundcloud() traceback through the SoundCloud client request. Read the linked SoundCloud security update to understand the 401 response. Done means SoundCloud tracks resolve successfully and the failure no longer reaches download_file() as a None URL.
