Hide the spline fine-tuning flags from CLI help

Browse Source 
--corner-threshold, --segment-length, and --splice-threshold are still
accepted but no longer listed, and their -c/-l/-s short forms are gone:
the defaults serve virtually every conversion, and --simplify supersedes
them as the knob that actually moves output size (sweeping segment
length 3.5..=10 shifts the sample photo by 25% alone but under 2% once
simplify is on). README options block synced with the new help text.
