Feature: Unique `sid` (session ID) for each stream URL entry so that multiple streams can be watched simultaneously

[dogganon]

When all streams share the same sid only the last loaded stream is available, the rest becomes empty.

Steps to reproduce

• Generate a shared sid using a UUID generator.
• Construct stream URLs:

https://cfd-v4-service-channel-stitcher-use1-1.prd.pluto.tv/stitch/hls/channel/65775e07dfed030008cb3f47/master.m3u8?appName=web&appVersion=unknown&clientTime=0&deviceDNT=0&deviceId=6c263251-30d3-11ef-9cf5-e9ddff8fe497&deviceMake=Chrome&deviceModel=web&deviceType=web&deviceVersion=unknown&includeExtendedEvents=false&serverSideAds=false&sessionID={SID}&sid={SID}

where {SID} is the generated UUID.

• Play both streams in separate tabs at https://hlsjs.video-dev.org/demo.
• Open DevTools on both tabs; Watch for "Fatal error"s.

Expected results

• DevTools Console: The stream that loads last will be the one that plays without the "Fatal error: levelEmptyError".
• DevTools Network: The one that fails keeps loading empty M3U8 playlists.

Notes

I have also tried different deviceIds for each stream but that didn't seem to do anything.

Hypotheses

• sid controls the streaming session, regardless of the deviceId.
• Only one stream may be active for an sid at any given time; new streams opened with the same sid will "steal" the session from the old ones.

Can you provide some information on how you're playing the streams?

Multiple streams with the same ID work for me. If you're playing streams on multiple devices, each device should have a unique ID, otherwise you will have issues.
