This pull request introduces several updates to streamline the network_plot function, improve modularity, and enhance test coverage. The most significant changes involve refactoring the network_plot implementation to delegate functionality to si_graph_plot, simplifying its interface, and adding utility functions for better reusability.

Refactoring and Simplification:

• shapiq/plot/network.py: Refactored the network_plot function to delegate most of its functionality to si_graph_plot, removing redundant code and simplifying the function's interface. Several arguments, such as first_order_values, second_order_values, and feature_image_patches, were removed, and a generic **kwargs was introduced to pass additional parameters. [1] [2] [3]

Dependency Updates:

• pyproject.toml: Added pillow as a dependency to support image processing functionality.

Utility Enhancements:

• shapiq/plot/utils.py: Added a new utility function add_image_in_center to handle the addition of images in the center of plots, improving reusability and modularity.

Testing Improvements:

• tests/conftest.py: Introduced a new pytest fixture, example_values, to provide reusable interaction values for testing.
• tests/tests_plots/test_network_plot.py: Removed redundant tests for network_plot that relied on now-deprecated arguments and added reliance on InteractionValues objects for testing. [1] [2]

Code Cleanup:

• shapiq/plot/network.py: Removed unused imports and large blocks of obsolete code related to graph construction and legend management.
