Function to_geo_layer_from_aux_text 

pub fn to_geo_layer_from_aux_text(text: &str) -> Result<GeoLayer>

Transform the Substation table in PowerWorld AUX text into a geographic layer without exposing the component parser’s borrowed AuxFile type.

Rows without a finite number, latitude, and longitude are skipped. A valid AUX document with no usable substation coordinates returns an empty layer.

Errors

The AUX section syntax is malformed.
