Erosion Improvements / 2024 Working Docker

[Ygryega]

river_erosion Improvements:

Consistency in Naming and Formatting:
    Standardized variable names and formatting for readability.
Handling Elevation Values:
    Ensured elevation values are handled correctly to avoid invalid states.
Inclusive Loop Ranges:
    Adjusted loop ranges to cover all relevant points more effectively.
Debugging Information:
    Added detailed debugging messages for easier troubleshooting.
Addressed Issues:
    Fixed potential elevation handling issues and loop inclusiveness.

river_flow Improvements:

Encapsulation of Logic:
    find_nearest_river: Added helper function to merge with nearby rivers.
    handle_wrapping: Added helper function for world boundary wrapping.
    add_path: Added helper function to manage path updates and current location.
Simplified Flow Control:
    Reduced nested conditions to improve function readability and maintainability.
Improved Readability:
    Minimized complexity and deep nesting by breaking tasks into smaller functions.
    Ensured consistent variable naming and formatting.
Enhanced Error Handling:
    Provided clearer error messages and improved handling of unexpected cases.
Efficient Path Management:
    Streamlined path management using add_path to reduce redundancy.
Addressed Issues:
    Improved handling of edge cases and avoided spawning impossible rivers (lakes).

cleanup_flow Key Improvements:

Initialization:
    Set celevation to float('inf') initially to include the first point.
Elevation Adjustment:
    Corrected elevation values to ensure smooth flow.
Remove Isolated Points:
    Added logic to remove points that do not fit the flow pattern based on neighbors.
Explanation:
    cleaned_river: Ensured elevation consistency and adjusted values as needed.
    final_river: Removed isolated points by checking neighbor validity, keeping valid points only.
