KenM76andClaude Opus 5.5 38c9482191 fix(xfa, create): read a BMP's pixels from after its headers when its offset points into them ...

LiveCycle Designer wrote BMPs whose file header gives bfOffBits = 0. image
(0.25) seeks to that offset as given, so the pixels were read from the file
header on and the picture was drawn shifted and wrapped around (#4937).

`pdfcraft_xfa::image::bmp_with_pixel_offset` recomputes the offset from the
info header (its size, BI_BITFIELDS masks in a 40-byte header, the palette)
when the declared one lies inside the headers and the computed one fits in
the file; anything else is passed through unchanged and not copied. XFA
pictures (size and decode) and `create::from_images` both go through it, so
pdfcraft-create gains a dependency on pdfcraft-xfa (L4 -> L3).

Fixes #4937
