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.

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.

Fixes timestamps in several cases where they were being processed
incorrectly, which was causing some chunked audio files to mis-report
timestamps into the past or the future, which caused the seekbar to jump
around in an unpredictable way.

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.

We were forcing a resampling ratio to match the HRTF filter supplied
with the app, now we resample the HRTF to match the input audio, which
will be resampled to match the output device settings.

It's more like the output monitor thread, since it only monitors output,
rather than actually handing the output callbacks.

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.

Now there's a configuration dialog for tweaking the settings
in semi-real time. Everything that can be changed without
restarting is changed without restarting, otherwise the audio
pipeline is reset, which happens quickly enough anyway.
Awaiting translation to Spanish, other languages have been
removed pending their maintainers fixing most of their
problems, which includes me being lazy and AI translating
bits so I could rush updates.

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.

It should be deriving its channel count from the file format,
since it's applied before any other filters.

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

Shuffle around @autoreleasepool blocks, and also add one
to the audio processing code in the playback callback, so
audio memory is released during playback instead of
accumulating.

A stopped instance of OutputCoreAudio should not continue to feed the
visualization system with stale audio, potentially while another instance
is already starting up and feeding its own audio output.

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 output may prove to have lower latency, but the results are too
glitchy to really be usable. Not even visualization latency is handled
correctly.

Resampler flush may indefinitely produce 1 sample if there is a rounding
error with the buffering calculations. Work around this.
Signed-off-by: Christopher Snowhill <kode54@gmail.com>
When the clipped sample rate changes, the resampler needs to be
restarted. This was previously failing because the target sample rate
wasn't changing.

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

Another large stack buffer was at play here. Consolidated it into an
existing buffer that can perform double duty here, since neither place
