Add TGS File Converter and Renderer Support to lottie-web

This feature will implement support in lottie-web for handling TGS files, including a converter that transforms TGS (Telegram animated sticker) files into a format compatible with lottie-web, and allows direct rendering of TGS animations in web environments. The implementation should include:

• TGS file parsing and validation
• Conversion of TGS data to lottie-compatible JSON, if necessary
• Integration with the lottie-web rendering pipeline, so users can load and display TGS files just like standard Lottie JSON files
• Documentation and sample usage for developers
• This feature will enhance lottie-web by enabling seamless rendering of Telegram stickers and expanding animation format compatibility.
