Extend qChecksum calculation
ISO 14443-3 is for nfc communication and uses 2 different checksums.
The existing one is from ISO 3309 and the other one is from ITU-V.41.
Both are needed to implement an own transport layer defined in ISO
14443-4 to allow nfc commands with a length above 250 byte independent
from the smartphone.
This change will avoid code duplication in QNearFieldTarget.
The private function qNfcChecksum is a copy of qChecksum.
