Updates to parse_uspto.py

[skearnes]

• More stringent validation of reaction SMILES
• Failing Reactions are saved to a separate file
• Disables RDKit logging in validate_dataset.py so it can reasonably be used to validate the output

Note that these changes were used to generate https://github.com/open-reaction-database/ord-data/pull/59
