Add mic resetting to default mic log watcher + notification when it happens

[64766C]

Sometimes a headset mic can reset due to some system issues. For me this reset happens completely silently and it's very difficult to notice. VRChat writes a log when it happens:

2022.02.24 22:15:18 Log        -  [Always] uSpeak: OnAudioConfigurationChanged - devicesChanged = True, resetting mic..


2022.02.24 22:15:18 Log        -  [Always] uSpeak: SetInputDevice by name 'Digital Audio Interface (Valve VR Radio & HMD Mic)' (1 total)

Alright I will look into adding it as an event if it's useful.

Just to add a little bit of context why I think it's useful. When this happens, it's completely silent and there is no indication at all from Windows or VRChat about the fact that your input was just changed to a different microphone. There is no device disconnected or connected system sound for example.

So something goes on in Windows -> microphone changes silently in the background -> you are now effectively muted in game or at best talking from your desktop mic. For me my headset mic is the default and it doesn't pick up any sound from across the room. The only way I can notice this has happened is that my mouth no longer moves in game and the red mic icon doesn't light up when is speak.

Okay this does sound useful, my only concern would be people that switch their default sound card often spamming them with unwanted notifications, I will try this in next beta release and see how it goes.

Give this build a try and tell me how it goes. https://github.com/Natsumi-sama/VRCX/releases/tag/v2022.03.21
