/**
* Inits a raw Wwise vorbis stream.
*
* Vorbis packets are stored in .ogg, which is divided into ogg pages/packets, and the first packets contain necessary
* vorbis setup. For raw vorbis the setup is stored it elsewhere (i.e.- in the .exe), presumably to shave off some kb
* per stream and codec startup time. We'll read the external setup and raw data and decode it with libvorbis.
*
* Wwise stores a reduced setup, and the raw vorbis packets have mini headers with the block size,
* and vorbis packets themselves may reduced as well. The format evolved over time so there are some variations.
* The Wwise implementation uses Tremor (fixed-point Vorbis) but shouldn't matter.
*
* Format reverse engineered by hcs in ww2ogg (https://github.com/hcs64/ww2ogg).
* Info from the official docs (https://www.xiph.org/vorbis/doc/libvorbis/overview.html).
