Create the Result type for the Morphir SDK

Provide a `Result` type for the morphir SDK that is compatible with the result type in elm/core:

- [ ] Result - see [elm/core Result](https://github.com/elm/core/blob/master/src/Result.elm)
- [ ] Result tests - see tests - https://github.com/elm/core/blob/master/tests/tests/Test/Result.elm

## Implementing

This will most likely involve aliasing F#'s core `Result` type.
Where possible `inline` can be used to directly map to `Result` type functionality.
