feat(ethereum): < -adds new eth tx type

[gskapka]

...per title.

The up and coming dencun fork implements EIP4844 which introduces a new receipt type for blob-carrying transactions.

This PR allows parsing of such transactions, and includes a new test with a goerli block containing the new type of txs.

LGTM!

Some notes:

• This PR only updates the transaction type, block validation is still missing. Sentinel cannot validate a block an EIP4844 block.
• Reviewing the PR, I noticed that type 2 transactions are mislabelled. They should be EIP1559 and not EIP2718. The latter, introduces the field TransactionType. EIP1559 introduces type 2 transactions with new fees https://eips.ethereum.org/EIPS/eip-1559

Noted re point one. That will come in a following PR.

Re point two - fixing now, & will tag for re-review once ready.

Updated. Note that I had to update one of the submission materials - I'm not sure why but the original one for an eth mainnet block but where the type field in a receipt was a string: EIP2718. Re-pulling that submission material now shows the correct field: type: "0x2", which parses correctly with the updated ReceiptTypes enum, and so I've replaced that submission material test sample.

Updated to include backwards compatible bug fix for the wrong EthReceiptType.

LGTM!
