feat: refactored PhotonImage API to instance methods with simplified naming

- Refactored PhotonImage API from standalone functions to instance methods with simplified naming conventions.
- Renamed PhotonImage.new_from_byteslice() to parse() for a simpler, more intuitive factory method API.
- Converted PhotonImage.get_width() and get_height() methods to width and height getter properties.
- Consolidated four separate encoding methods (getBytes, getBytesJpeg, getBytesWebp, getBytesGif) into a single encode(format, quality) method.
- Moved resize() from a standalone function to a PhotonImage instance method.
- Added ImageFormat enum to specify encoding formats (PNG, JPEG, WEBP, GIF) in the encode method.
- Removed manual resource management via free() and Symbol.dispose, simplifying PhotonImage lifecycle.
