Fix: Reauthenticate with SiriusXM when playing a station

[btoconnor]

This attempts to address music-assistant/hass-music-assistant#3165

As stated on the issue:
I think the problem is that we authenticate with SiriusXM when the server starts up so that we can confirm authentication details, and load the list of channels. However, the sxm session expires frequently. By the time the user attempts to play a station, there's a decent chance that the session is expired. The sxm-client will attempt to re-authenticate automatically, but by the time this happens, there's a decent chance ffmpeg will raise a TimeoutError.

This patch makes it so that the code preemptively attempts to re-authenticate with SiriusXM before handing over the m3u8 playlist, ensuring that there is a valid session. It's possible this will cause a slight delay to start the feed, but in my (limited) testing, this was fine, and still preferable to the TimeoutError being raised.

@btoconnor Could you check this as pytest is failing?

[btoconnor]

Looks like those are failing on jellyfin tests

[OzGav]

Yeah sorry I only glanced at it. Doesn’t seem your problem!

[btoconnor]

@OzGav anyway to rerun these tests? I can't seem to find anything on my end. I can push up a dummy commit if necessary, or I can just wait and do nothing 🙃

Yeah I think wait for Marcel
