* Partial voice implementation on audio renderer
* Implemented audren resampler (based on original impl)
* Fix BiquadFilter struct
* Pause audio playback on last stream buffer
* Split audren/audout files into separate folders, some minor cleanup
* Use AudioRendererParameter on GetWorkBufferSize aswell
* Bump audren version to REV4, name a few things, increase sample buffer size
* Remove useless new lines
* Add support for events, move concept of domains to IpcService
* Support waiting for KThread, remove some test code, other tweaks
* Use move handle on NIFM since I can't test that now, it's better to leave it how it was
