Following review feedback, the reader now rejects a header claiming a
width or height beyond 65536, guarding against malformed byte streams
that would otherwise trigger an unreasonable allocation. The writer
stays full 32-bit ('unlimited'), and native little-endian order and the
transparency mask are kept as-is. Adds Ruby and Python tests for the
oversized-header rejection.
