Cannot import name 'blackbody'

[iancrossfield]

When calling result = jdi.run_pandexo..., the following error is thrown:

/home/exolab/anaconda3/lib/python3.9/site-packages/pandexo.engine-1.5.3.1-py3.9.egg/pandexo/engine/create_input.py in module
6 import astropy.constants as c
7 import os
----> 8 from astropy.modeling import blackbody as bb
9 import warnings
10 with warnings.catch_warnings():

ImportError: cannot import name 'blackbody' from 'astropy.modeling' (/home/exolab/anaconda3/lib/python3.9/site-packages/astropy/modeling/init.py)

This seems to be because astropy deprecated their old 'blackbody' module:

Hi all! Thanks for submitting this and sorry for the long delay. PandExo 2.0 is staged in dev and nearly ready for release. Look out for it soon.
