## Link to GitHub Issue, if one exists
Fixes#509
## Description of change
Implement `WrappedIAudioClient3`.
For now, we have only seen SDVX use it (EG final) and only when the
shared mode patch is enabled. Exclusive still goes through version 1.
This means that for V3 we can forego implementing backend conversion
logic (for now).
Only significant addition is `InitializeSharedAudioStream` and this IS
called by SDVX when shared mode patch is enabled.
## Testing
Tested EG final, tested year 1 data, also IIDX shared/exclusive wasapi.

#477
## Description of change
Arena cab has two sound cards and it uses `WrappedIMMDeviceCollection`
to set the volume to 100% on boot on both, instead of the typical
`GetDefaultAudioEndpoint`.
## Testing
Testing Delta, testing other games as well as they are affected.
