Cancel all open orders for the authenticated account.
Cancellation requests require L2 authentication headers: KUEST_ADDRESS, KUEST_SIGNATURE, KUEST_TIMESTAMP, KUEST_API_KEY, and KUEST_PASSPHRASE.
The response always returns HTTP 200 OK. Successful cancellations append the ULIDs to cancelled. If any order cannot be cancelled, it appears in notCanceled with a short reason string.
