Wojciech Kapsa 505f48f237 decklink: Add new persistent-id property and sort devices by persistent ID
The order of the devices iterator from the SDK is undefined and can
randomly change.

Keep the device-number property for backwards compatibility and
simplicity but prefer the persistent-id property and also use it for the
device provider implementation.
