Code Review
This pull request refactors the PNG signature representation in APNGImageGenerator from a raw uint8_t array to a std::array<uint8_t, 8> and exposes it publicly. This allows for safer and cleaner usage across the generator implementation and unit tests, replacing raw pointer/size operations with standard library container methods. Feedback is provided to use triple-slash comments (///) instead of double-slash comments (//) for the documentation of the signature member to comply with the Flutter style guide.
