Based on the C++11 code by Joel Yliluoma / bisqwit, which in turn is
based on information from NX-Engine. I have also taken the liberty of
bundling the required wavetable bank and PixTone drums. Contrary to the
documentation provided with the code, my version of dou_1006.zip, as
downloaded over a decade ago, had the wavetable bank at offset 635,816
bytes into the file, not 1,115,748 bytes. Possibly a difference of
having applied the translation patch? My copy is the original version,
so I had to use a real resource parser to locate the waveforms.
The player will obey the configured sample rate, loop count, and fade
time for synthesizers, and also obey Repeat One to play indefinitely.
The code should be quite robust to minor abuses, though I can't imagine
how well it would hold up to random bad files, other than playing
outright garbage.

This should fix some potential initialization errors it may have had
before, but this doesn't fix the broken Sound Canvas VA plugin. Roland
says it's supposed to be broken on macOS 12+ and/or Apple silicon
anyway, so I guess there's no dodging that.

There has been an API in GME to detect tracks ending for quite some time
now, and this just adds a little bit to the existing comment, which
previously noted that there was no way to detect if a track had ended,
which may have been true several major versions of GME long past.

The output has been assigning twice as many samples as it was supposed
to ever since commit 8d851e5bda, which
ended up generating the correct 1024 samples (2048 per GME parameter),
but assigned 2048 to the AudioChunk, which resulted in over-reading the
audio buffer, and thankfully not crashing, but instead causing an awful
sound distortion effect as random memory contents were played as PCM
audio.

The SID builder needs a static initializer, otherwise multiple instances

This is an unnecessary step, and results in the offset being off by the
duration of the first pre-read block. This is incorrect.

The Vorbis, Opus, MAD MPEG, and especially the FFmpeg inputs needed to
have their metadata update intervals severely reduced, to reduce CPU
usage, especially on files with lots of tags. Interval reduced to only
once per second.

It already supported reading the CUESHEET metadata block, but I managed
to break reading and processing CUESHEET Vorbis comments, which broke
CUE tagging, as well as files that didn't have both tags.

The local and seekable file scanner could crash on bad MPEG files if
they failed to decode any frames and broke due to either end of file or
other unrecoverable errors, due to a division by zero error attempting
to calculate the file bitrate. Now correctly return error state if this
occurs, bailing early.

- Updated libFLAC to the latest Git commit, post 1.3.4.
- Updated libid3tag to 0.16.1.
- Updated libopus to the latest Git commit.
- Updated my FFmpeg libfdk-aac patch. Previously was overwriting
memory when it was supposed to be skipping samples.
Also added debug versions of several of the libraries, and changed
the library extractor script to unpack the debug libraries over the
release set to add the particular matching debug versions when
