title: rollup-plugin-typescript does not recognize 'lib' in 'compilerOptions'
body: <p>I'm following <a href="https://hackernoon.com/how-to-create-library-in-angular-2-and-publish-to-npm-from-scratch-f2b1272d6266" rel="nofollow noreferrer">this tutorial</a> for creating an npm package.  Here is my tsconfig.json:</p>
  
  <pre><code>{
      "compilerOptions": {
          "target": "es5",
          "module": "es2015",
          "sourceMap": true,
          "moduleResolution": "node",
          "emitDecoratorMetadata": true,
          "experimentalDecorators": true,
          "declaration": true,
          "outDir": "./dist",
          "lib": ["es2015", "dom"]
      },
      "files": ["./lib/empty-text.ts"]
  }
  </code></pre>
  
  <p>When I run rollup I get this error:</p>
  
  <pre><code>rollup-plugin-typescript: Unknown compiler option 'lib'.
  [!] Error: rollup-plugin-typescript: Couldn't process compiler options
  Error: rollup-plugin-typescript: Couldn't process compiler options

      at Object.&lt;anonymous&gt; (D:\sandbox\rollup-play\rollup.config.umd.js:45:9)
  </code></pre>
  
  <p>When I remove <code>lib</code> from <code>compilerOptions</code>, I get a different set of errors.  I'm using rollup v0.8.1.  Does this version not support <code>lib</code>, if it does, what am I doing wrong?</p>
