Add Builtin::CoatedFogra39 ("Coated FOGRA39 (fitted, craft-cms)",
profiles/craft-coated-fogra39.icc: AToB 11^4, BToA 33^3, 330% TAC,
medium GCR). It is fitted to Fogra's FOGRA39 characterisation data
(tests/data/FOGRA39.txt, unmodified, 1617 patches): a Yule-Nielsen
Neugebauer model with free overprints, per-ink tone curves and n, plus
a Gaussian-kernel ridge correction of the residuals. Against the
patches, relative colorimetric through the AToB: mean dE00 0.07,
p95 0.18, max 0.53. The BToA tables invert the AToB table
(synth::cmyk_profile_from_model); the Photocraft coated profile and its
synth defaults are unchanged.
Builtin::from_profile_name maps the names documents carry for
FOGRA39-based profiles (Coated FOGRA39, ISO Coated v2 (ECI)) to the new
profile and every built-in by its description. Adds math::delta_e2000.
