Add gain metadata to the galsim_galaxy hdf5 and fits file outputs #22

This information is needed as part of the DM stack analysis to create the variance image of the MaskedImage data structure. We could take a variance image as input but for now I think it is easiest just to create the variance image as the Image/gain.

@wadawson I added an interface in the commit 05ec0373d5cba86d1f1827c0babba698af66109f to save a gain value in the segments file. Can you check what other feature(s) you had in mind for this issue?
