This commit changes the `String<kSize>` class to inherit from `StringWriter` class. It helps simplify their use allowing `StringWriter` methods to be directly called on an `String` instance while ensuring the implementation is still shared among all template variants of `String<kSize>` class. This change also ensures that `String<kSize>` is always initialized and set to an empty string from its constructor.
