auro-badge: add tsconfig support

[blackfalcon]

Is your feature request related to a problem? Please describe.

The element does not support typescript users.

Describe the solution you'd like

Update the repo to support typescript. The solution is to use the typescript npm package, add a types npm build script and create a tsconfig.json file.

tsconfig.json example

{
  "include": ["src/**/*.js"], // process the generated JS files from the src js files 
  "exclude": [],
  "compilerOptions": {
    // Tells TypeScript to read JS files, as
    // normally they are ignored as source files
    "allowJs": true,
    // Generate d.ts files
    "declaration": true,
    // This compiler run should
    // only output d.ts files
    "emitDeclarationOnly": true,
    "outDir": "dist",
    // go to js file when using IDE functions like
    // "Go to Definition" in VSCode
    "declarationMap": true
  }
}
