The reader should have been skipping the properties of CUE sheets when
reading the referenced data for the inner files.

For big endian sample formats, endianness can be swapped using Clang
specific byte swap functions, which are present in all supported
versions of Xcode.

Simple upmixing algorithms now use Accelerate framework functions
instead of complex loops, and the HRIR filter now supports forcing
stereo output to any channel output configuration that has at least
front stereo speakers.

Where TagLib is not being employed, use FFmpeg to read tags where
possible. This allows reading tags from files like IFF. It reads it
through properties, otherwise allowing tag readers to function like
usual.

This resulted in horrible things, the generic N to N upmixer was leaving
unmapped channels as uninitialized memory. This fixes horrible things
happening for people with interfaces with more channels than the source
file, frequently when the source file is stereo, or if the file is mono
and a center channel is present.

HTTP Reader now supports limited seeking backwards even in streams, so
seek back to file start for repeated file tests, since there are at
least a few inputs that all claim to support things like Ogg containers.

_mm_malloc and _mm_free are apparently based on intrinsic functions,
and only exist on Intel or older macOS targets. So removing them in

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
restart playback if they change output device formats.

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

The ChunkList wasn't clearing the remover entered flag when the chain
was empty. Now it does, so it will shut down correctly.

Code ordering was wrong, it was writing the output samples repeatedly
for each input speaker, now it will only write them once.

By applying copious amounts of autorelease pools, memory is freed in a
timely manner. Prior to this, buffer objects were freed, but not being
released, and thus accumulating in memory indefinitely, as the original
threads and functions had autorelease pools that scoped the entire
thread, rather than individual function blocks that utilized the new
buffering system. This fixes memory growth caused by playback.

The volume should have been twice what it was, because I got this scale
wrong. The correct scale for Accelerate inverse FFT is 1/4 per sample,
not 1/8 like I accidentally misread while rewriting a convolver for the
umpteenth time from scratch.

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.

This is a fixed point implementation identical to Microsoft's original
algorithm. Or at least I assume it's Microsoft's. It was actually
adapted from hdcd_decode.exe, which was adapted from somewhere else.
It's entirely in fixed point math now, so it's fairly deterministic.

Flush the resampler when the source file terminates, so that it outputs

Replace individual virtual buffers with large _mm_malloc blocks at a

This seals up a major memory leak of the playback state whenever a chain
is released on stop or on manual track change. CogAudioMulti was
retaining the input node due to its listeners, and InputNode was not
releasing the listeners when asked to stop running. This is fixed now.

The thread wait on shutdown had the potential to lock up waiting for the

the thread should progress to shutdown a lot quicker.
