AdultSwim and some other sites stream with playlists that break into segments because of ads.
For example: https://files.videohelp.com/u/107659/layer6_wv.m3u8

So layer6_wv.m3u8 contains wm_6_0.mp4 AND wm_6_1.mp4. That's the same for the video and audio (layer7_wv_0.m3u8).

n_m3u8dl-re is confused by this and only grabs the first part, but decrypts it. yt-dlp throws an error with --allow-u saying "Initialization fragment found after media fragments, unable to download".

I found the browser extension "Live Stream Downloader" can download these, but it's several extra steps.
For a half hour show I need Live Stream Downloader to get both video segments, both audio segments, decrypt all 4 parts separately, merge the segments then the tracks.

Is there anything that can do this at a Windows command-line? I find it strange that n_m3u8-dl doesn't manage this already.
