A strongly typed alexandria data value

Because alexandria is written in Rust, all data is strongly typed, and can be checked for being a certain type via dynamic dispatch (unfortunately monomorphic generics kinda end at the disk sync level).

Value types can be nested with Value::Map, which contains a BTreeMap<_, _>. Nestings can be arbitrarily deep.
