* Disable stereoheadseteffects and stub out all known code references via define
By effect this also completely removes Headset sound options from the game config, as it serves no purpose whatsoever compared to stereo.
Because it's stubbed out everywhere rather than only the necessary locations to prevent it, this should boost audio runtime slightly for everything, not just the stuff that actively used it.
* Rename DISABLE_HEADSET_STEREO_EFFECTS to ENABLE_HEADSET_STEREO_EFFECTS
* Reorganize and reduce audio Note struct
* Add performance to define description
* Rename ENABLE_HEADSET_STEREO_EFFECTS to ENABLE_STEREO_HEADSET_EFFECTS
Vanilla's ramping table sounds absolutely horrendous, most noticeably when it comes to slow volume fade-ins/outs. By default, precision has been increased by 4x vanilla US, which overall has an insignificant impact on performance. This is still half as precise as EU's volume ramping table, that's about the point where additional memory and performance aspects are impacted more significantly.
This allows sounds to start instantly without any fade-in. Using new soundbanks with delay values of 0 will not compile with base decomp, but old decomp-compliant soundbanks will work with this commit.
Refactored everything to be more memory efficient and execute fewer function calls than prior
Also accidentally discovered a significant bug with the audio modes always being forced to stereo so this is definitely 2.1 scope lmao
