Specified

Representation of an Option with a specialized purpose of whether a value is specified or not.

This has 2 main benefits:

1. You can define a function like def doStuff(a: Specified[Int] = Specified.WasNotSpecified): Unit = ??? and then call it like: doStuff(5) because of the given Conversion
2. You have the ability to represent both Specified[Int] and Specified[Option[Int]]. This is very useful when it comes to things like partial updates. With only the ability to represent Option[Int], you are often left stuck with being able to update to Some(_), and None means no update.
3. You can tell the difference between: {} // Specified.WasNotSpecified { "field": null } // Specified.WasSpecified(None) { "field": 5 } // Specified.WasSpecified(Some(5))
