SNEWPY does not support init_model when called in sim_tester.ipynb

[jakob2508]

When executing the sim_tester.ipynb file in /scratch I get the following error

`NameError Traceback (most recent call last)

It appears that the current version of SEWPY no longer supports to import the module function init_model as defined in /python/asteria/source.py

try: from snewpy.models.util import init_model except ModuleNotFoundError: from .util import init_model as init_snewpy_model_from_param
