Christopher Snowhill 34884d825a [Audio Processing] Move float32 converter
Move the Float32 converter to a different location, for any future plans
to support decoding audio files to common data for any other purpose.

Christopher Snowhill 8af32e8d2e Replace Core Audio output with Core Media runtime
The output now uses AVSampleBufferAudioRenderer to play all formats, and
uses that to resample. It also supports Spatial Audio on macOS 12.0 or
newer. Note that there are some outstanding bugs with Spatial Audio
support. Namely that it appears to be limited to only 192 kHz at mono or
stereo, or 352800 Hz at surround configurations. This breaks DSD64
playback at stereo formats, as well as possibly other things. This is
entirely an Apple bug. I have reported it to Apple with reference code
FB10441301 for reference, in case anyone else wants to complain that it
isn't fixed.

Christopher Snowhill 4537a72275 [DSD] Add pure downsampling path, disabled
Pure downsampling is slower, but may or may not be more accurate. Though
probably not worth it. It did help me realize a minor error, though.
The decimator's volume is twice as loud as it should be.

Christopher Snowhill 777ab28d6a Replaced libsoxr with r8brain free source
Replaced the free SoX resampler with the r8brain resampler source, which
is also free.

Christopher Snowhill 728c44242c Do not reset output sample rate automatically
This was buggy as hell, and resulted in errors. Now the user should
restart playback if they change output device formats.

Christopher Snowhill 477feaab1d Now properly supports sample format changing
Sample format can now change dynamically at play time, and the player
will resample it as necessary, extrapolating edges between changes to
reduce the potential for gaps.

Currently supported formats for this:

- FLAC
- Ogg Vorbis
- Any format supported by FFmpeg, such as MP3 or AAC

Christopher Snowhill 637ea4efe1 Core Audio output: Rewrote major portions
After all this rewriting, down or upmixing the audio is now handled with
the lowest latency possible, meaning that toggling the HRIR option now
takes effect immediately.

Christopher Snowhill e7b78085ca New feature: Implemented headphone virtualization
This new virtualizer uses the Accelerate framework to process samples.
I've bundled a HeSuVi impulse for now, and will add an option to select
an impulse in the future. It will validate the selection before sending
it to the actual filter, which outright fails if it receives invalid
input. Impulses will be supported in any arbitrary format that Cog
supports, but let's not go too hog wild, it requires HeSuVi 14 channel
presets.
