Feat: Refactor ShipParams for Efficient Array Operations and Update Tests

[pankaj-bind]

This update addresses the issue of inefficient and repetitive array operations within the ShipParams class (in WeatherRoutingTool/ship/shipparams.py).

Problem:
The ShipParams class contained highly repetitive code in methods like define_courses, select, flip, expand_axis_for_intermediate, get_element, get_single_object, and get_reduced_2D_object. Each numerical attribute was individually handled for array manipulations, leading to verbose, error-prone, and difficult-to-maintain code.

Solution:
The ShipParams class has been refactored to introduce dedicated class attributes (_numeric_array_attributes and _non_numeric_array_attributes). These lists enable an iterative approach to array operations, replacing the redundant, individual attribute manipulations with a more generic and concise loop-based implementation. This significantly reduces code duplication.

Benefits:

• Improved Maintainability: Easier to add or modify ship parameters without extensive changes across multiple methods.
• Enhanced Readability: The code is more concise and the core logic is clearer.
• Reduced Redundancy: Eliminates repetitive lines of code, making the codebase leaner and less prone to inconsistencies.
• Reduced Risk of Bugs: Ensures consistent application of array operations to all relevant attributes.

Test Updates:
The tests/test_ship.py file has been updated to align with these changes.

• The test_shipparams_get_element method's tuple unpacking has been adjusted to match the new order of attributes returned by ShipParams.get_element.
• A minor syntax error in the message array initialization within both test_shipparams_get_element and test_shipparams_get_single has been corrected.

This refactoring improves the overall quality and robustness of the ShipParams class.
