This PR contains the work done to add a location at a time and updates the locations in the list of locations screen right after. To give further details about the work done: - [x] implemented the `LocationProvider` provider in the **Persistence** library; - [x] implemented the `SaveLocalLocationUseCase` use case; - [x] defined the properties and functions of the `LocationsAddViewModeling` protocol to support the clean, updating and saving of locations; - [x] implemented the `LocationsAddViewModel` view model; - [x] implemented the `LocationsAddViewController` view controller; - [x] implemented the dismissal of the `LocationsAddCoordinator` coordinator.
