What is the new behavior?

• Added a check that allows indexing transactions with v < 35 if included in WHITE_LISTED_EIP_155_TRANSACTION_HASHES.
• Added unit tests.

An error is no longer thrown for each transaction with v < 35, but due to this check in ethers, v must be equal to 27 or 28, otherwise LegacyTransaction.fromTxData will fail.

I don't know if we want to only index the white listed ones, that seems like a bit much what do you think @tcoratger? They shouldn't pass the rpc nor the execution layer so I think filtering a third time on the indexer is a lot

@greged93 I was thinking maybe in the past, on some specific transactions if we reindex everything from the beginning but I agree that it's a lot. As you can feel, both options are fine with me.
