Interpolate over defects in an image
Parameters
----------
maskedImage : `lsst.afw.image.MaskedImage`
Image on which to perform interpolation.
psf : `lsst.afw.detection.Psf`
Point-spread function; currently unused.
defectList : `lsst.meas.algorithms.Defects`
List of defects to interpolate over.
fallbackValue : `float`
Value to set when interpolation fails.

Interpolate in place over pixels in a maskedImage marked as bad.
Pixels to be interpolated are set by either a mask planeName provided
by the caller OR a defects list of type `~lsst.meas.algorithms.Defects`
If both are provided an exception is raised.
Note that the interpolation code in meas_algorithms currently doesn't
use the input PSF (though it's a required argument), so it's not
important to set the input PSF parameters exactly. This PSF is set
here as the psf attached to the "image" (i.e if the image passed in
is an Exposure). Otherwise, a psf model is created using
measAlg.GaussianPsfFactory with the value of fwhmPixels (the value
passed in by the caller, or the default defaultFwhm set in
measAlg.GaussianPsfFactory if None).
@param[in,out] image MaskedImage OR Exposure to be interpolated
@param[in] planeName name of mask plane over which to interpolate
If None, must provide a defects list.
@param[in] fwhmPixels FWHM of core star (pixels)
If None the default is used, where the default
is set to the exposure psf if available
@param[in] defects List of defects of type ipIsr.Defects
over which to interpolate.

Context manager to potentially transpose an image
This applies the ``transpose`` configuration setting.
Transposing the image allows us to interpolate along columns instead
of rows, which is useful when the saturation trails are typically
oriented along rows on the warped/coadded images, instead of along
columns as they typically are in raw CCD images.
Parameters
----------
maskedImage : `lsst.afw.image.MaskedImage`
Image on which to perform interpolation.
defects : `lsst.meas.algorithms.Defects`
List of defects to interpolate over.
Yields
------
useImage : `lsst.afw.image.MaskedImage`
Image to use for interpolation; it may have been transposed.
useDefects : `lsst.meas.algorithms.Defects`
List of defects to use for interpolation; they may have been
transposed.
