Generate eigenimages that are normalised and background-subtracted.
The background subtraction ensures PSF variation doesn't couple with small background errors.
Reimplemented from lsst::afw::image::ImagePca< ImageT >.

Update the bad pixels (i.e.
those for which (value & mask) != 0) based on the current PCA decomposition; if none is available, use the mean of the good pixels
mask | Mask defining bad pixels |
ncomp | Number of components to use in estimate |
N.b. the work is actually done in do_updateBadPixels as the code only makes sense and compiles when we are doing a PCA on a set of MaskedImages
