MFKey32 key recovery incomplete key

When computing the key out of the nonces in the final stage of the MFKey32 recovery, the resulting key is 8 bits too short.

See attached screenshot for details. The key has only
5.5 bytes and not the required 6 bytes.

Bug ID from the app is

Did you try prepending a zero?

4 I think?

Should be fixed in 1.6. Could you check please if you still have those nonces?
