Smartlock V2 support

[giejay]

On my MacBook its not working because it doesn't do much after I select pair:

Adding peripheral Nuki_1554930D to try-to-pair queue
Timeout. Aborting pairing.
Pairing failed: pairing timeout

On my Raspberry Pi Zero:

ERROR while connecting Nuki_1554930D
Pairing failed: Error: Command Disallowed (0xc)
