Nuanced types

[oscartbeaumont]

Specta needs some way of tracking types at a lower level.

Eg. How to express the difference between Date and String (for the TS exporter) or Vec vs HashSet (for the Rust exporter)

Maybe something like:

impl DataType {
    /// TODO
    pub fn is<T: Type>(&self) -> bool {
        todo!();
    }
}

However, idk how that works for something like chrono/uuid which uses PrimitiveDataType instead of their own types. Maybe we should post-process them instead of pre-processing stuff.
