…shuffled non-exported members to the bottom of the file, and renamed a few test constants to aid readability. Also used it.each for multiple test cases.

@matthewwalsh0 thanks for the review! I made all of the changes you recommended, except for validating chainId !== 0, as I think this should be an API concern, rather than a utility concern, and the redundant "should" in the test names 👀 |

EIP-7702 defines a new struct
Authorizationwhich represents authority to set a pointer to a contract address at an EOA - effectively making the EOA perform as a smart contract.This change adds methods to hash and sign authorizations, and to recover signer address.
Although the EIP defines the signed authorization as
[chain_id, address, nonce, y_parity, r, s], the utility method returns the signature as a standardr|s|vsignature for consistency with other signing methods.See https://github.com/ethereum/EIPs/blob/master/EIPS/eip-7702.md for details
