Function resample_onto 

pub fn resample_onto(
    data: &[f64],
    src_dims: (usize, usize, usize),
    src_affine: &[f64; 16],
    dst_dims: (usize, usize, usize),
    dst_affine: &[f64; 16],
) -> Option<Vec<f64>>

Resample continuous data (magnitude, an unwrapped field, χ) from one grid onto another. Returns None if the source affine is singular.
