image - the barcode image holding the encoded and signed DCC

Returns:

the DCC payload

Throws:

DGCSchemaException - for DCC schema errors

SignatureException - for signature verification errors

CertificateExpiredException - if the DCC has expired

BarcodeException - for errors reading the barcode

IOException - for errors decoding data, for example CBOR related errors
