Akka.Serialization.Hyperion 1.4.15

Maintenance Release for Akka.NET 1.4** Akka.NET v1.4.15 introduces a new module, Akka.DependencyInjection, which will replace Akka.DI.Core and all of the libraries which depend on it. This seemed like the easiest way to preserve backwards compatibility - simple deprecate the old package and replace it with a new one. So what does Akka.DependencyInjection do differently than Akka.DI.Core? 1. **Allows users to pass in an [`IServiceProvider`](https://docs.microsoft.com/en-us/dotnet/api/system.iserviceprovider) into the `ActorSystem` before the latter is created, via [a new kind of programmatic configuration `Setup` that was introduced in Akka.NET v1.4](https://getakka.net/articles/concepts/configuration.html#programmatic-configuration-with-setup)**. This ensures that the `IServiceProvider` is immutable within an `ActorSystem`, a problem that we have currently with Akka.DI.Core. 2. **Makes it easy to access the `IServiceProvider` via the `Akka.DependencyInjection.ServiceProvider.For(ActorSystem)` method**, which is what we can use to get access to the service provider in order to consume required services inside our actors. 3. **Makes it possible to dependency inject some parameters will dynamically specifying some others**, something that users have been asking for since 2015.
