Add SRT/FLV/RTMP support and update documentation

Introduced Python scripts for SRT subtitle checking and fixing, and added comprehensive documentation covering advanced features such as protocol detection, subtitle/audio/quality management, keyboard shortcuts, and touch gestures. Updated local settings to allow new build and Python commands, added TypeScript definitions for FLV, and implemented RTMP/FLV protocol support in the player. Removed CHANGELOG.md and made various improvements to styles and example app.
