Adapt Variant M3U Format (EXT-X-STREAM-INF)

[seniordevel]

Describe the bug
I subscribed to a working m3u radio URL, but no sound.
The URL works fine in Firefox browser or Radio droid app:

https://wdrhf.akamaized.net/hls/live/2027994/wdr3/master.m3u8
(offical german radio station, always available)

Steps to reproduce the behavior:

1. Go to 'for you', press +

2. Name: wdr3, Link: https://wdrhf.akamaized.net/hls/live/2027994/wdr3/master.m3u8

3. Press subscribe

4. Go to 'for you' and tap wdr3

5. No sound, though media volume is on and maximum

Expected behavior
Radio sound should be there
