HistoricFeedDoneCallback (eBus 7.4.0 API)

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface HistoricFeedDoneCallback
```
An eBus client implementing IEHistoricSubscriber may choose to implement this functional interface as a private method instead of implementing the public IEHistoricSubscriber.feedDone(EHistoricSubscribeFeed.HistoricFeedState, EHistoricSubscribeFeed) method. This private HistoricFeedDoneCallback method is then passed to EHistoricSubscribeFeed.Builder.doneCallback(HistoricFeedDoneCallback).
Note: this callback may only be set when building an EHistoricSubscribeFeed instance. Once built, the feed done callback target may not be changed.

Note: failure to implement IEHistoricSubscriber.feedDone or to pass a HistoricFeedDoneCallback method to Builder.doneCallback results in a Builder.build() failure.
