If a FITS file doesn't have any WCS information in it, we default to a PixelScale. This is currently done silently.
This PR adds a warning that is emitted by default when reading this via FitsWCS(file), but is suppressed by default when reading via galsim.fits.read(file).
If you want to get the warning, you can now do galsim.fits.read(file, suppress_warning=False), and it will emit the warning. (So you can potentially catch it and do something particular if this happened.)
