Support for co-simulation fmus

[dhblum]

When instantiating a model with a co-simulation FMU, the following error is received:

Traceback (most recent call last):
  File "test_model.py", line 144, in test_instantiate_model_cs
    self.__instantiate_model(fmi_ver='cs')
  File "test_model.py", line 99, in __instantiate_model
    m = model.Model(filePath)
  File "/home/dhbubu/git/estimationpy/EstimationPy/estimationpy/fmu_utils/model.py", line 97, in __init__

KeyError: 'LSODAR_options'

This issue will address this error to provide limited support for co-simulation fmus.
