suunto_nautic: value subscriptions (UnsynchronisedLogs / BusyState) - #6

Conversation
…cations The dive /Data stream is a Whiteboard subscription (0x10 subscribe, 0x08 reply with the current value, 0x01 notifications, 0x11/0x09 unsubscribe), as an official-app capture on a Nautic S and an Ocean shows. Value resources such as /Logbook/UnsynchronisedLogs and /Sync/BusyState use the same framing; expose subscribe, unsubscribe and wait_notification so a host can sync when the watch reports new logs.

suunto_nautic_device_subscribe,suunto_nautic_device_unsubscribeandsuunto_nautic_device_wait_notificationto the public Nautic header.Why: an official Suunto app capture (Nautic S pairing, Ocean new-activity) shows that what the driver calls the /Data "stream" is a Whiteboard subscription:
0x10subscribes to a resource handle and is answered by0x08with the current value, the watch pushes0x01notifications,0x11unsubscribes (0x09reply). The app subscribes to/Logbook/UnsynchronisedLogs(uint16 count) and/Sync/BusyState(uint8) on every connect and syncs when the count rises and the watch isn't busy. These calls let libdc-swift do the same (deepsealabs/libdc-swift#45).[type:u16 LE][value](notifications carry one trailing pad byte).FF FF FFhandle) returnsDC_STATUS_UNSUPPORTED.Covered by libdc-swift's fake-watch tests (SuuntoNauticTransportTests). Needs on-watch confirmation that notifications arrive on a real Nautic/Ocean.
