* Add unit tests for NWWaitingHandler Motivation: Closes #589. Since we already have a public initializer for NIOTSNetworkEvents.WaitingForConnectivity, we should add unit tests for the handler now that it's straightforward. Modifications: The tests are in their own file `Tests/NWWaitingHandlerTests.swift`. * Bump swift-nio-transport-services to 1.13.0 * SwiftFormat@0.48.8 * Apply suggestions from code review Co-authored-by: David Nadoba <dnadoba@gmail.com> --------- Co-authored-by: David Nadoba <dnadoba@gmail.com>
