Update: GeneralDataLoadingViewModel now can handle state changes and result of data source. Previously it was possible only in view controller.
Add: GeneralDataLoadingHandler protocol, that defines methods for common data loading states handling.
Add: resultObservable and resultDriver properties to GeneralDataLoadingViewModel.
Add: hidesWhenStopped option to SpinnerView, so you can stop animation without hiding image inside it.
Update: Migrate to Swift 4.2 & Xcode 10. Update dependencies.
