Issue with branch 0xv2 support on ingest

[alejoloaiza]

Hi, I'm trying to validate the signature of an order using the ingest.go but it seems there is an issue with the api, it shows the signature is not correct, any ideas?

I raised an issue on the SRA documentation website. That signature is malformed for a couple of reasons.

That aside, this order would be rejected because:

• It's expired
• The feeRecipientAddress is not considered valid by OpenRelay
• The exchangeAddress is the 0x v1 exchange contract address, but the order is formatted for 0x v2.
