`StructElement` does not have the most convenient possible way to check for the existence of a field #41

While reviewing PR against another library that consumes IonElement, I observed that it would be nice to be able to check for the existence of a field in a struct without having to call StructElement.getOptional(String) and checking the return value for null.

Ideally, a StructElement.hasField function that returns a boolean value exists.
