Utils reorganization

[glenn-jocher]

This PR reorganizes the utils directory, creating a more specialized separation of tasks into a finer grained distribution of utils files. Four new files are created. This will allow for better readability and segregation of future ML tasks, i.e. classification and segmentation, which will require additional metrics, losses and plots.

• utils/autoanchor.py
• utils/metrics.py
• utils/loss.py
• utils/plots.py

🌟 Summary

Refactored the YOLOv5 codebase to tidy up modules and improve maintainability.

📊 Key Changes

• Moved plot_one_box from utils.general to utils.plots
• Introduced new modules utils.autoanchor, utils.loss, utils.metrics, utils.plots
• Removed redundant imports and comments
• Changed increment_path to use integer instead of ambiguous 1e3
• Organized code by separating functions into appropriate modules
• Deleted the redundant evolve.sh shell script

🎯 Purpose & Impact

• 🔃 Better Code Organization: Splitting utils into multiple modules improves code readability and modularity.
• 🧹 Cleaner Imports: Cleaning up imports reduces namespace cluttering and potential for import-related bugs.
• 🚀 Maintenance Efficiency: More manageable codebase, supporting faster future development and debugging processes.
• ❌ Removed Redundancy: Deleting the unused shell script and comments declutters the repository, streamlining the developer experience.
