Reproduce fake line overlap issue

[vargad]

No fix yet, contributing a failing test:

    let intersection = intersect(
            &geo::Line::new(
                geo::Coordinate{ x: 0.0, y: 0.0 },
                geo::Coordinate{ x: 0.0, y: 100.0 },
            ),
            &geo::Line::new(
                geo::Coordinate{ x: 0.0, y: 100.0 },
                geo::Coordinate{ x: 0.0, y: 200.0 },
            ),
        );
    println!("intersection: {:?}", intersection);

I would expect it to give one overlapping point: (0.0, 100.0)

intersection: Some(Line { start: Coord { x: 0.0, y: 100.0 }, end: Coord { x: 0.0, y: 200.0 } })
