Add dealloc function to close the file container, in case the caller

Refine the output function a bit, including adding some minor safety

Restrict the use of workgroup joining and workgroup intervals to macOS
Monterey or newer, as it seems the way I use it, it's completely broken
on macOS Big Sur, which was the original minimum target for the API.

Apply changes to exit the thread if workgroup initialization or joining
fails, instead of attempting to continue executing the thread.
Signed-off-by: Christopher Snowhill <kode54@gmail.com>
Add an extra step to the workgroup exit call, so that it only calls to
leave if the join token is valid, or at least initialized.

It was a fun ride, but I think I want to try something different. Users,
please be sure not to have DNS blocking for Crashlytics if you want me
to have any useful bug reporting info if it crashes on you, or otherwise
blows up. Otherwise, I don't get any useful data to help me fix crashes.

Synchronize audio setup and audio stopping on the object's own pointer,

The changes include no longer leaving the workgroup for seeking or for
converter format changes, and also still leaving the workgroup on thread
termination if there was an error with intervals starting or finishing.

An impulse cache reduces any glitching from format channel count changes
to near insignificant levels, resulting in a more pleasant experience
when there are different mixed formats playing, or even a file which
changes format mid-playback.

Ensure that dynamic info updates, even on static files, only update the
exact track they apply to, by atomically assigning the userInfo property
before opening the decoder, so that callbacks to the player indicate the
correct track and don't assume it's the one that's currently visibly
playing. Fixes start of track metadata notifications from overwriting
the previously playing track.

DFT should use aligned memory blocks for best results. Also allocate one
extra sample for DFT output, just in case DFT zop is as bad as zrop.

Work back to a vDSP implementation, this time using overlap-save instead
of overlap-add, also accumulating the results as complex values, only
inversing them once at the end, and finally, replacing the FFT method
with the newer DFT API.

Errors should stop all attempts to further use the audio thread priority

As the decimator has shown to be twice as loud as it should be, the
volume should be reduced by half when converting DSD to PCM with it.

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.

This prevents crashes where inputs were not returning either properties
or metadata blocks and the file open cache was attempting to cache the
resulting nil pointer as if it were valid. Also prevent the metadata
redundant string coalescing from processing nil objects as well, in case
it's used that way somewhere else.

Set baseline real-time priority for audio threads even on old macOS,
since that API is available there. Only set it once, and do not attempt
again if it fails, only once per thread.
Signed-off-by: Christopher Snowhill <kode54@gmail.com>
I'm not sure about macOS Ventura, but stable releases of macOS, at
least on Intel, require that threads joining Audio Interval
workgroups already be set to run as real-time before joining. Not
doing this results in an uncaught exception and a crash.
