Update to new major version of APNSwift

[code28]

Updates the dependency to the new major version of APNSwift and new location for the package.

This is a major release because of API changes but should be backwards compatible for the most part.

Given APNSwift contains a breaking change that most people will hit I don't think we should do this. Most people aren't going to choose which version they take and they only depend on this library so this will likely be a breaking change. If we're going to add a breaking change we might as well remove support for v3 altogether

Agreed. I just merged a major change into Apnswift so it's time

Thanks for your fast reaction! No problem, I'm totally fine with releasing a new major version and removing support for v3 of APNSwift! The change is applied.

@kylebrowning what's changed in the new major version of APNSwift? Basically do we need to update https://docs.vapor.codes/advanced/apns/

I'm not kylebrowning, but I think I can answer as well, since my PR made the new major version necessary: Only the handling of (custom) loggers changed. Since logging of APNS is not covered in the Vapor docs, maybe only the version number should be updated, but otherwise it's fine.

Original comment: With this change, the new major version of APNSwift is enabled, so that the user can decide on their own, if they want to use version 3 or 4 of APNSwift.

Both should work without any changes in this repo, so I decided to use the range in the Package.swift. If you prefer to release a new major version here as well, it'd be fine for me, too.

Cool, so this is good to go other than CI not triggering. I'll take a look at it later unless you want to have a go
