binding: identity: read vin and user token from nfc tag
Original idea and rework from Scott Murray for CES 2019 (funky flounder). This is a simplified version to match agl-service-nfc which in master is not providing all tag record fields but just the content value. To test an nfc tag must be programmed with a text record with value vin:uid.
