/// Apply flat field calibration to a readout
///
/// This function applies the flat field calibration to the input readout.  Support is available for different
/// image types, though the input and flat images must have the same type.  The relative offsets between the
/// input and flat images is determined from the readout row0,col0 and the CELL.X0 and CELL.Y0 concepts.
/// Normalisation of the flat is left as the responsibility of the caller.  Non-positive pixels in the flat
/// are masked, if there is a mask present in the input readout.
