YoursFunny 85fb12edc7 refactor(photo): read the PNG header with the png crate ...

parse_png_header hand-decoded the IHDR — byte offsets, the depth byte's five legal values, the color byte's five — roughly thirty lines the png crate already implements (and validates properly: CRC included). It is now Decoder::new + read_info, which is all the header a plan needs; no pixels are decoded. The synthetic test fixture gained the IHDR CRC and an IDAT header (read_info stops at the first IDAT; the hand parser stopped four bytes earlier and checked no CRC), with a nine-line reflected CRC-32 alongside it; the assertions on width/height/depth/color are unchanged, as are the real-file cases.
