Function vsharp_isotropic 

fn vsharp_isotropic(
    field: &[f64],
    mask: &[u8],
    grid: &Grid,
    h: f64,
    radii: &[f64],
    deconvolve: Option<f64>,
    ball: VsharpBall,
    progress: impl FnMut(usize, usize),
) -> (Vec<f64>, Vec<u8>)

V-SHARP with the background estimated on an isotropic grid of spacing h mm anchored at the mask’s bounding box (see the module docs).
