This PR proposes that we change the ccdproc tutorials in two related ways:

  1. Use astropy.visualization instead of a custom notebook-specific show_image
  2. Remove the convenience_functions.py from the ccdproc notebooks (since they are only used for show_image, anyway)

My thinking here is that this now actually showcases astropy.visualization so people learn that it exists over the course of these tutorials, and makes the notebooks entirely standalone, which in general is good practice IMHO.

cc @mwcraig who I think originally wrote this and might have a dissenting option (although git says it was 5 years ago so it pre-dates the astropy.visualization functionality...), or perhaps @larrybradley who more recently modified these notebooks.

I'm fine with the change.

I wasn't involved in writing these notebook (I only fixed an astropy import issue 4+ years ago), but I completely agree with using astropy.visualization tools.
