This should fix an exception being thrown because the observer wasn't
registered, or known to be registered. Only register it when it will be
used, and only unregister it if it was registered.

Apparently, this doesn't work too well with real HDCD tracks, and causes
all sorts of weird volume issues. Just leave the volume alone, and let
HDCD decoding make tracks louder, possibly, rather than try to halve the
volume automatically on a detector that isn't terribly good.

And disabled by default, at that. I can't actually hear the difference
of Peak Extension in the Rock track I have that claims to use it. And
Low Level Range Extension is more trouble than it's worth on tracks that
use it by mistake, or maliciously, if the case may be. I may add track
tag level control in the future.

This code did not check the number of samples in a packet before adding
it to the output buffer, which apparently had the potential to cause the
output code to emit up to 512 samples of silence between tracks. This,
as one can guess, is a bad thing, and causes noticeable gapping between
tracks.

Output logging, a debugging feature that is only enabled at build time
if I need to chase down some audio mixing or output bug, was not logging
anything at all. Change to use Cocoa file writing methods, and actually
implement the output writer function again.
This code is left disabled 99% of the time anyway, and especially in
release builds. Like the node logging code elsewhere, it has the
potential to be very noisy and consume massive amounts of disk space.

This should be included, for safety purposes, in case the rounding up to
the nearest multiple of 256 samples doesn't bump the buffer size enough.

The double members should be ordered first so they are aligned to an 8

The Visualization Manager PCM/FFT copy function was already observing
these parameters for null input and only returning output to the ones
which were not null. This just makes it clear that they are both
optional parameters. This is useful for future visualization adventures,
allowing PCM copy without invoking the FFT processing, or requesting FFT
without also having to keep the PCM.
This is mostly only a compile time change, and has no noticeable effect
on the current runtime behavior, as the only consumers of the Visualizer
data currently request both PCM and FFT.

This affects User Defaults, but only has any effect on ChunkLists which
are being used for conversion, and only if they're processing DSD source
material. Thus, the observer should only be added on the one stream that
is converting DSD, and should definitely be removed when the object is
deallocated.
This fixes a serious crash bug that mostly appears to only affect Intel
Macs, and has no major side effects on Apple Silicon that I can tell.
It's a good thing I still own an Intel Mac or two to test on, even if
they are both trapped on older releases of macOS.

The converter doesn't just require an output format call, it also
requires this input format change callback to actually signal it to
reopen the converter process with a new format setup.

Output format mostly requires stopping and restarting the output device,
and this also prevents us from using the latency function properly,
which apparently always returns 0 for output devices anyway. These
changes also prevent the output callback from hanging when resets occur.

Move the DSPs to the output node, so they don't get closed and reopened
