* Updated `SpotifyClient.PlayerResolveDeviceId` method to raise a `SpotifyApiError` error if the specified device value could not be resolved.

* Updated `SpotifyConnectDevices` model to include a `DateLastRefreshed` property that indicates when the device list was last refreshed.

* Updated `SpotifyClient.GetSpotifyConnectDevices` method to store results to the configuration cache.

* Updated `ZeroconfConnect.Connect` method to provide a small delay after processing the Spotify Zeroconf API command, which will give the device some time to process the change.
* Updated `ZeroconfConnect.Disconnect` method to provide a small delay after processing the Spotify Zeroconf API command, which will give the device some time to process the change.

* Updated `SpotifyClient.GetSpotifyConnectDevices` method to retrieve dynamic Spotify Connect devices as well as static devices. Dynamic devices are Spotify Connect devices that are not found in Zeroconf discovery process, but still exist in the player device list. These are usually Spotify Connect web or mobile players with temporary device id's.

* Added `SpotifyClient.GetSpotifyConnectDevices` method that gets information about all available Spotify Connect player devices (not just ones controlled by a user).
