sgio.core.mesh.check_isolated_nodes(mesh: SGMesh | Mesh)

Check if there are isolated/unconnected nodes in the mesh.

Go through all cells and check if every node is used at least once.

Create a list of cell ids for each node:

node_cell_ids = [
    [
        (cell_block_id, cell_id_in_block),
        ...
    ],
    ...
]
