plotting.py calls non-existing pysiaf function

[tonysohn]

plotting.py has the following line:
aps_imaging, aps_spectra, aps_coron = pysiaf.siaf.get_main_apertures()

This results in an error (in the View Observatory Field of View In Aladin.ipynb notebook) since there is no function called get_main_aperture in pysiaf.siaf.

did I not pull request this in? I guess I never made a pull request with that. Huh, thanks. Will do.

[tonysohn]

You mean in pysiaf? Nope, I only see PR for find_apernames from you.

Whoops - clearly I missed a pretty important step here. :-)
