Support Optimism Transaction Receipt Fields

*Making sure this is logged ahead of v2 engine* Optimism requires additional fields from the transaction receipt in order to correctly calculate gas fees and transaction revenue. Fields to be added: 'l1GasUsed', 'l1GasPrice','l1FeeScalar'. Etherscan mappings are attached below for reference. Since these fields are not pulled in currently, they are approximated and can be inaccurate at times.
