Title: Force astropy output longitudes to 0 ... 360 deg range

I noticed that the satrapy Galactic longitutes are sometimes negative, whereas the output for all other longitudes in 0 .. 360. To be tidy and have easier comparison it makes sense to compute the astropy output longitudes also for the 0 .. 360 deg range, which I did here.

This PR has a two problems:
* I accidentally branched `astropy-positive-longitudes` off of my `kapteyn` branch, so now I have those commits in this PR also. Will this resolve itself once `kapteyn` is merged or do I need to fix this? How can I fix this?
* The output coordinates in the txt files are slightly different on different machines, so a simple line-by-line diff is not very useful. I think we simply have to accept that, probably trying to only give so many digits that these rounding differences never show up is a bad idea?
