Function vector_potential_triangle_mesh_mapping_par 

pub fn vector_potential_triangle_mesh_mapping_par(
    obs: (&[f64], &[f64], &[f64]),
    mesh: &TriangleMeshView<'_>,
    out: (&mut [f64], &mut [f64], &mut [f64]),
) -> Result<(), &'static str>

Parallel variant of vector_potential_triangle_mesh_mapping.

Args: obs: Observation point component slices (x, y, z) (m). mesh: Borrowed triangle-mesh geometry view. out: Output mapping buffers (ax_map, ay_map, az_map) (Vs/(mA)), each row-major in (observation point, source node) order.

Returns: Ok(()) after writing the dense mapping to out, or an error if the mesh geometry or slice dimensions are inconsistent.
