Updates

Version 1.1 changes

• Got rid of unneeded imports
• load_ref_model doesn't need an argument any more to load a model.
• canonical and canonical_smiles now return None for invalid smiles.
• Added get_fcd as a quick way to get a the fcd score from two lists of smiles.

Version 1.2 changes

• Ported the package to pytorch with the help of https://github.com/insilicomedicine/fcd_torch
• pytorch allows a lighter package and is more popular than Tensorflow which saves an additional install
