Helper functions for spatial networks

get_edge_weights	Extracts edge weights from a spatial network for a specified weight attribute and returns them as a numpy array.
get_nodes_and_labels	A function to extract node indices and labels from a spatial network.
get_node_node_distance	Retrieves node-node distance information from a spatial network's distance cache for a specified weight attribute and an optional subset of source nodes.
node_node_distance	Computes the shortest path distances from a set of source nodes to all other nodes in a spatial network, with optional caching to avoid redundant computations.
update_node_node_distance_cache	Update the node-node distance cache in the spatial network with new distances for a given weight and limit.
remove_nodes_from_distance_cache	Removes specified nodes from the distance cache of a spatial network.
shortest_path_length_node_a_to_node_b	Computes the shortest path distance from node_a to node_b in a spatial network using Dijkstra's algorithm, with the specified edge weight.
clear_distance_cache	Clear the distance cache of a spatial network.
batched_dijkstra	Compute shortest path distances from multiple source nodes to all other nodes in the graph using Dijkstra's algorithm in batches.
