Lint uploaded election file and localStorage data to confirm they match expected election object shape.

• Typescript Types or JSON Schema should generate the other. Options:
  • JSON to Typescript: json-schema-to-typescript - article: Statically Typed Data Validation with JSON Schema and TypeScript
  • Typescript to JSON: typescript-json-schema
• Add new App validateElection(election: Election) method and use it to validate the election object when it comes from any source: uploaded file, localStorage, etc.
• Replace the App componentDidCatch() method (from Bug: Clear localStorage if there is an error with the data. #104) with call to new App validateElection(election: Election) method which can then trigger the App reset() method before rendering and causing the error.

We need to think about how to connect json schema to typescript type.
