Hello 👋

I would like to index trades that happen on blur. Is it possible to get `OrdersMatched` event struct and other structs that go inside that one so I could parse on-chains events?

```auto
event OrdersMatched(
	address indexed maker,
	address indexed taker,
	Order sell,
	bytes32 sellHash,
	Order buy,
	bytes32 buyHash
)

struct Order {
    address trader;
    Side side;
    address matchingPolicy;
    address collection;
    uint256 tokenId;
    uint256 amount;
    address paymentToken;
    uint256 price;
    uint256 listingTime;
    /* Order expiration timestamp - 0 for oracle cancellations. */
    uint256 expirationTime;
    Fee[] fees;
    uint256 salt;
    bytes extraParams;
}

struct Fee {
    uint16 rate;
    address payable recipient;
}

enum Side { Buy, Sell }
