d1a6f373cb Refactor CD-DA flow by removing intermediate buffers and loops 
Thanks to @ripsaw8080 for insight into CD-DA channel mapping,
@hail-to-the-ryzen for testing and flagging a position-tracking bug,
and @dreamer_ for guidance and code review.

The CD-DA volume and channel mapping loops were moved to generic mixer
calls and no longer require a pre-processing loop:
 - Application-controlled CD-DA volume adjustment is now applied using
   an existing mixer volume scalar that was previously unused by the
   CD-DA code.
 - Mapping of CD-DA left and right channels is now applied at the tail
   end of the mixer's sample ingest sequence.

The following have been removed:
 - The CD-DA callback chunk-wise circular buffer
 - The decode buffers in the Opus and MP3 decoders
 - The decode buffer and conversion buffers in SDL_Sound
These removals and API changes allow the image player's buffer
to be passed-through ultimately to the audio codec, skipping multiple
intermediate buffers.

84eaccc517 slight refactoring, so that it is easier to correctly increase TICK_SHIFT above 16. 
Maybe 24 will be a nice value, judging from the tests.
