AEP import: Lumetri Color's master RGB curve, Hue vs Sat and colour wheels

After Effects 2026 presets made by hand (1200 lumetri-58 ... -62) decode
the data the scripted samples could not set.

- RGB curve (-0039): the first of the four curves is the master curve
  and arrives as curves/rgbCurves/master. A moved red, green or blue
  curve is reported: no sample tells which slot is which channel.
- Hue vs Sat (-0042): y is the offset from neutral, 1 doubling the
  saturation (in linear light), so EffectCraft's y is 0.5 + y / 2. The
  other four hue / saturation curves stay reported when moved.
- Color Wheels (-0047): four triples of hue (degrees), brightness slider
  (0.5 neutral) and distance. Shadows, Midtones and Highlights become
  EffectCraft's wheel colours (HSL of that hue, saturation = distance,
  lightness 0.5); the brightness sliders and the fourth wheel are
  reported.
- Damaged curve or wheel data is reported as damaged.
- Legacy Tone And Saturation is reported when a record says on: its pard
  default turns from off to on when the project is saved again (the
  25.x / 24.x / 26 copies of 1200), so comparing with it missed it.
- The Input LUT and Look presets confirm -0095 / -0096 hold the names;
  the LUT files are After Effects' own and are not embedded.

Evidence: the 62 read-backs still equal the imported values in the new
63-composition 1200 file. The version copies store the same Lumetri
definitions, ranges and values and give the same report. Renders: master
curve within 0.024 (After Effects uses a natural spline, EffectCraft's
Lumetri a monotone one), Hue vs Sat mean 0.008, wheels mean 0.042.
