Add Docker support and configuration for SRS SIP

- Created a new README_cross.md file with Docker build instructions.
- Updated srs.conf to include logging configuration options.
- Added docker-compose.yml to define the SRS SIP service with necessary ports and volume mappings.
- Introduced config.yaml for general and GB28181-specific configurations.
- Added initial srs.conf with settings for RTMP, HTTP API, and WebRTC support.
