6ABOS: 6S-based Atmospheric Background Offset Subtraction v1.1.0 - Modular Architecture

6ABOS v1.1.5 - LakeWater Model & RTM Optimization Key Improvements New Reflectance Models: Added support for the LakeWater ground reflectance model. Optimized for aquatic remote sensing via the --lakewater flag. Enhanced Progress Tracking: Integrated a real-time dynamic progress bar in the CLI with ETA and band-specific status updates. Physical Range Clipping: Implemented strict physical constraints [0, 1.1] for surface reflectance to eliminate atmospheric noise in absorption bands. Intelligent Aerosol Logic: The engine now prioritizes Maritime aerosol profiles when the LakeWater model is active for improved physical consistency. Code Quality: Full refactor for PEP 8 compliance, including English docstrings and standardized variable naming. Fixes Improved datetime parsing for EnMAP metadata to support ISO UTC strings. Optimized task distribution in ProcessPoolExecutor for better CPU utilization.
