get_alasky_image module

This script will download astronomical images in FITS format from the Alasky server. Potential HIPS data sets can be found at https://aladin.u-strasbg.fr/hips/list One annoyance is that if the specified data/image cannot be retrieved it will still return a FITS file but with nothing useful in it.

In theory one should be able to retrieve a file by giving a full URL to the astropy file name, but that does not seem to allow specification of timeouts and I find PyCurl more reliable.
