feat: Add setDeviceId method on web

[dganzella]

Added setDeviceId method, so the output speaker (HTML5AudioElement sink ID) can be set -- so developer can select which device to play sound instead of default

[ryanheise]

I would suggest renaming this to setWebDeviceId following the convention of setWebCrossOrigin since it is a web-specific method. Or given that it's specific to the web API, maybe setWebSinkId so there is no confusion about what it represents? If you're thinking of generic naming so that multiple platforms can implement it in a different way, I think there are too many platform differences in the way audio routing APIs are designed that this would not work. Maybe there is a similar notion in Android, but in just_audio it is again named androidAudioSessionId as it is unlikely Android's API works in a similar way to other platforms (for example, you don't set it, you listen to it and then pass it into separate APIs for routing.)

k, I will fix it this week and send to you

Did you have an opinion on setWebDeviceId vs setWebSinkId? I think "sink" is more faithful to the original API.

Yes, I also think setWebSinkId is better!

[ryanheise]

Then let's go with the setWebSinkId naming, and then I can merge and release.

ok @ryanheise I moved this PR to another, because I needed to revert the pubspec.yaml but did not want to change the code that is working in production to stop compiling
