Some naming convention changes, many bug fixes, some updates in the utility of the thing
The GalfitModule reg tests are now also up to date again but more unit tests will be added in the future (also to come, additions using Python's unittest library). That being said they're running slow/hitting the timeout limit, so it may be due to using some old FITS files. I will investigate and may update these again in the future.
Importantly, there's an update to preprocessImage.m to accommodate re-using the ellipse fit from a pre-2016 SpArcFiRe run since no bulge info was output back then. I have also therefore updated the matlab executable.
