Move the DSPs to the output node, so they don't get closed and reopened
across each file. Also restructure the output handler to buffer a little
on its own, to account for track switch activity.

This required some minor workarounds to deal with the play time counting
that works toward play count reporting.

Cleaned up project settings to current defaults, except for the macOS
deployment version, which is still 10.13. Cleaned up a lot of headers
and such to include with angle braces instead of double quotes. Enabled
build sandbox in a lot of places. Disabled subproject signing in several
places, for libraries and frameworks which will be stripped and signed
when they are copied into place in the final build.
Also, while trying to solve compilation issues, the visualization
controller was reverted to the Objective C implementation, which is
probably faster anyway. Stupid Swift/Objective-C language mixing issues.

Seeking should clear the buffers completely now, and will be nearly
instant, depending on how fast the input can decode.

Seeking now mutes properly, and will not leave the audio muted across
other operations. Audio output changes should also mute and destroy the
buffers of the input chain, so that the audio resets properly.

Visualization now buffers in the audio output pipeline, and uses a
container system to delay multiple buffer chains from emitting
visualization data over top of each other. This should stabilize
display output significantly, while introducing minimal lag before
DSP configuration changes take effect.

Audio Chunks now have full timestamp accounting, including DSP playback
speed ratio for the one DSP that can change play ratio, Rubber Band.
Inputs which support looping and actually reporting the absolute play
position now do so.

The last of the built-in processors is now in the threaded processing
chain, and all DSPs are marked high priority and with short buffers.

This class can more flexibly process and emit varying chunk sizes than
the previous code could, solving the problem of wide tempo changes.

I will implement the more complex setup of providing options for
most of the configuration that Rubber Band provides, at a later
date, when I feel like creating a complex configuration dialog
for it, and asking for help translating every option and setting.

Implements a simple speed control using a resampler
designed for real time changes. A rubberband speed
control will be implemented at a later date.

This reverts usage of the AVFoundation output to use
the previous lower latency CoreAudio output, and
paves the way for a change I am cooking up soon.
Fixes several issues with playback and seeking latency.

This new method should cause all stops to default to immediate stoppage,
and only stops that occur after an end of track signal should indicate
to play out the entire buffer.

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.

Add play count data collection, including first seen times for every
file first added to the playlist. Data is indexed by album, artist, and
title, or by filename, whichever matches first. Add interfaces to
AppleScript automation definition as well.

Now the output is restarted on the current file at the current position
if the output format has changed. This should resolve the issue finally.

This was buggy as hell, and resulted in errors. Now the user should

Rewrite attempt number two. Now using array lists of audio chunks, with
each chunk having its format and optionally losslessness stashed along
with it. This replaces the old virtual ring buffer method. As a result
of this, the HRIR toggle now works instantaneously.

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.
