feat: add cyclonedx.model.crypto.ProtocolProperties.crypto_ref_array

applied the fix recommended in the thread, to add crypto_ref_array
as an argument to ProtocolProperties class
Also updated bom1.6.SNAPSHOT.xsd from cryptoRef -> cryptoRefArray
added testcase and BOM json from the mentioned issue.
