Hi, it would be great to have pickle support. The following snippet fails on python 3.7 and 3.8 using version 0.31 and 0.41 respectively.

>>> import pickle, pycld2
>>> pickle.dumps(pycld2.detect)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
_pickle.PicklingError: Can't pickle <built-in function detect>: import of module 'cld' failed

I am not familiar with C bindings for python, but maybe the error is related to using the wrong name for the module here

pycld2/bindings/pycldmodule.cc

Line 353 in e3ac86e

"cld", // m_name
