- Added optional logger parameter to various classes including `BaseDataCollector`, `CollectorManager`, `RealTimeCandleProcessor`, and `BatchCandleProcessor` to support conditional logging.
- Implemented error-only logging mode, allowing components to log only error and critical messages when specified.
- Updated logging calls to utilize new helper methods for improved readability and maintainability.
- Enhanced documentation to include details on the new logging system and its usage across components.
- Ensured that child components inherit the logger from their parent components for consistent logging behavior.
- Introduced the `OKXCollector` and `OKXWebSocketClient` classes for real-time market data collection from the OKX exchange.
- Implemented a factory pattern for creating exchange-specific collectors, enhancing modularity and scalability.
- Added configuration support for the OKX collector in `config/okx_config.json`.
- Updated documentation to reflect the new modular architecture and provide guidance on using the OKX collector.
- Created unit tests for the OKX collector and exchange factory to ensure functionality and reliability.
- Enhanced logging and error handling throughout the new implementation for improved monitoring and debugging.
