Variopinta 0.7.0

Variopinta 0.7.0

• Add LongestMaxSize for aspect-preserving resize with exact half-up dimension
  rounding, optional antialiasing, and shared image/mask geometry. Compose it
  with PadIfNeeded for square output without stretching.
• Accelerate constant padding for RGB and grayscale images and label masks,
  preserving fill values and output pixels.
• Renew benchmark evidence, record participant-specific resize rounding, and
  fix fingerprint coverage for tensor-output benchmarks.
