/* 
  cgbi2png.ts
  Convert Apple CgBI PNG ("iPhone-optimized PNG") to standard PNG.

  What this does:
  - Parses PNG, detects and removes the CgBI chunk (present before IHDR).
  - Concatenates IDAT data and inflates using raw DEFLATE (inflateRaw).
  - For color type 6 (RGBA, 8-bit):
      * Reverse PNG scanline filters to reconstruct pixels
      * Convert BGRA -> RGBA
