feat: use new typescript features to create setX y unsetX methods

BREAKING CHANGE: the properies are no longer set/unset using
`property.set()` or `property.unset()` methods. New methods follow the
convention `setProperty()` and `unsetProperty()`

BREAKING CHANGE: remove undocumented lazy constructor helper

 ### fromClassObject()
 
 Creates a new object builder from the given class. The properties that can be set are the same
-properties as the class has.

 When using this builder object is instantiated using `Object.create` so the function constructor is
 never called.
