- 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 a modular architecture for data processing, including common utilities for validation, transformation, and aggregation.
- Implemented `StandardizedTrade`, `OHLCVCandle`, and `TimeframeBucket` classes for unified data handling across exchanges.
- Developed `OKXDataProcessor` for OKX-specific data validation and processing, leveraging the new common framework.
- Enhanced `OKXCollector` to utilize the common data processing utilities, improving modularity and maintainability.
- Updated documentation to reflect the new architecture and provide guidance on the data processing framework.
- Created comprehensive tests for the new data processing components to ensure reliability and functionality.
