Function wafer::input::fill_data

fn fill_data(
    file: &str, 
    data: &Array3<R64>, 
    target_size: [usize; 3], 
    bb: usize, 
    log: &Logger
) -> Array3<R64>

Once data has been pulled from disk into a convertable format, we contstruct an array ready to calculate on. This requires the addition of a central difference buffer zone and may require the data to be resampled if input sizes differ from the size of the data on disk.
