fix(bundling): support exported array of options for rollup

[jaysoo]

This PR allows users to export an array of rollup options in rollup.config.js.

The e2e test shows an example:

module.exports = (config) => [{
...config,
output: {
  format: "esm",
  dir: "dist/test",
  name: "Mylib",
  entryFileNames: "[name].js",
  chunkFileNames: "[name].js"
}
}];
