Missing dependence on pysynphot

[rmjarvis]

I've been looking at the new WebbPSF code for rendering WFIRST PSF images here, and running their script, I got an ImportError from poppy:

$ python wim_psf_basic_f0v_even.py 
Script to generate WFIRST imaging PSFs for each SCA in the FPA
Please ensure that updates to the zernike file are copied to 
{$HOME}/Projects/WebbPSF/webbpsf-data/WFI/wim_zernikes_cycle8.csv
Traceback (most recent call last):
  File "wim_psf_basic_f0v_even.py", line 139, in <module>
    s_src = webbpsf.specFromSpectralType(sp_type, catalog='phoenix')
  File "/anaconda3/envs/py3/lib/python3.6/site-packages/poppy/utils.py", line 1433, in specFromSpectralType
    import pysynphot
ModuleNotFoundError: No module named 'pysynphot'

Installing pysynphot fixed the problem (or at least got farther before hitting a different error), but it seems like poppy is missing a dependence on pysynphot in the pip and/or conda specification. (I installed webbpsf via conda, which in turn installed poppy.)

Hi @rmjarvis, could you please re-file this issue on the spacetelescope repo: https://github.com/spacetelescope/webbpsf

That’s our main development repository now and is the best place to file issues. Thanks much for this report!

OK!
