AttributeError: 'str' object has no attribute 'decode' (scipy1.7)

[htalibart]

Hello,

When running the simple example provided in your wiki, CCMpred failed with the following error in ccmpred/algorithm/lbfgs.py, line 91, in minimize:
AttributeError: 'str' object has no attribute 'decode'
It seems to be because I am using a newer version of scipy (scipy1.7.1).

Replacing line 91 of ccmpred/algorithm/lbfgs.py:
"message": res.message.decode("utf-8"),
with
"message": res.message,
fixed it for me.
