Pull request overview

This PR introduces a small Exodus (netCDF) inspection utility to convert .exo meshes into a Python dictionary so tests can compare Exodus-based meshes structurally (rather than relying on binary .exo equivalence). It also refactors shared Exodus metadata parsing (get_exo_info) into the new utility module and updates the test suite to incorporate this comparison approach.

Changes:

• Added src/cubitpy/exodus_utility.py with convert_exodus_to_dict() and moved get_exo_info() there for reuse.
• Updated YAML comparison in tests to inline converted Exodus mesh data into the STRUCTURE GEOMETRY section when mesh_in_exo=True.
• Added a new unit test validating exodus-to-dict conversion for a minimal brick mesh.
