Create PlanetController and Presentation

## Description
The PlanetController and presentation will manage the invocation of the Gateways so that no game system interacts directly with the APIGateways. Their main responsibility is to bundle the functionality of anything related to planets.

**Add PlanetViewModel**
- EphemerisData
- PhysicalBodyData
- CaptureData

**Presenter**
- Make this also into a class

- Include presenter method for unsuccessful result (later will have this to handle different responses)

**Unit Tests:**
