splitfx: support --no-dither/-D option

splitfx is incapable of knowing in 100% of cases whether dithering
should be used (as it has no visibility into sox internals), so
support disabling it completely via command-line.
This is like the identical sox option, and passed to sox(1), too.

This feature is useful for splitting already-mastered 16-bit
recordings.
