pub fn read_gridfm_scenarios(dir: impl AsRef<Path>) -> Result<Vec<GridfmRead>>Expand description
Read every scenario from a gridfm dataset, one Network per scenario id
(sorted ascending) over the shared topology — the read side of the scenario
batch (#57). Each scenario is rebuilt independently, so two scenarios may
differ in branch status, bus types, and reference bus.
