New v3 API endpoint for getting check image data

We have introduced a new Get check image data (GET /v3/payments/{paymentId}/check-image) endpoint. You can now get images of an existing check sent to a vendor. From the response, use downloadLink in a GET request to download the front and back images of the check.

curl '{downloadLink}&sessionId={session_id}' \
--output {check_name}

See GET /v3/payments/{paymentId}/check-image in the API reference for more information.
