Expose `none` constructor #72

Internally, ValueBag includes a None variant, but there's no way to construct one. Typically in Rust you'd wrap a value in Option to express nullability, but since ValueBag itself is a container, it would be handy to have a way to distinguish between no value bag and a value bag with a None in it (in JavaScript for example the former is undefined, and the latter is null).
