Allow serialization of Galois field
I recently tried playing around with multithreading and noticed, that I can not pass the Galois field object to a thread, since the Galois class can not be pickled. An example error would be
PicklingError: Can't pickle <class 'galois.GF(47)'>: attribute lookup GF(47) on galois failed
