Is your feature request related to a problem? Please describe.

add_metapaths_by_weights() relies on dijstra's algorithm by scipy.sparse.csgraph.
While much faster than NetworkX, there could be space for improvement of the computational efficiency.

Describe the solution you'd like

• Support A* algorthm / Contraction Hierarchy
• Integrate rustworkx (as of now nx_to_rx() and rx_to_nx() are the only ones supported)

Describe alternatives you've considered

API changes

Additional context

• create_isochrone() with KNN-based concave hull is already improved by hashing strategy Improve create_isochrone() to allow multi centers / thresholds and refactor concave_hull_knn #139
