Christopher Snowhill 46ee7fc8b9 HDCD: Make HDCD extension processing optional
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.
