Optimize transaction watcher

[cgewecke]

Should be able to get tx.input from the data in the eth_sendTransaction payload and reduce reqs by 1.

Then fetch the receipt from the tx hash returned by the call.

• eth_sendRawTransaction needs to be decoded

  // Whatever the TS of this is...
  const utils = require('@ethersproject/transactions'); 
  const tx = utils.parse(rawTransactionHex);
  

• Make a waffle test

Questions

• Benchmark vs synthetix? They are running at ~10/12 min for 2200/2500 tests.
• How often is util.matchBinaries being called from the reporter to resolve ids?
