Signing

Call getSignature with message and privateKey:

const message = {
  from: 0x0000000000000000000000000000000000000000,
  nonce: 0,
  payload: [
    { to: "0x0000000000000000000000000000000000000000", value: 0, gasLimit: 0, data: "0x" }
  ]
};
const signature = getSignature(message, privateKey);

getSignature will sign EIP-712 hash of the following data:
