This PR contains the work done to implement some useful protocols, classes and extensions to use to setup a persistence layer in an application. To provide further details about the work done: - [x] declared the `Persistence` target in the Package file; - [x] forgot to declare the `Communications` and `Persistence` target to the `SwiftLibs` library in the `Package` file; - [x] defined the `Service` public protocol; - [x] implemented the `Fetcher` generic class; - [x] implemented the `bitBucket` static property in the `URL+Devices` public extension; - [x] updated the `README` file.
