Fix formatting of generated code within ESBuild

[ryanthemanuel]

What would you like?

Currently, the generated code does not have proper tabbing or new lines:

__commonJS["./lib/deferred.js"] = function(exports, module2, __filename, __dirname, require) {

let fs;
function __get_fs__() {
  return fs = fs || (require("fs", "fs", (typeof __filename2 !== 'undefined' ? __filename2 : __filename), (typeof __dirname2 !== 'undefined' ? __dirname2 : __dirname)))
}
  function accessfs() {
    return (__get_fs__()).readFileSync(__resolve_path(typeof __filename2 !== 'undefined' ? __filename2 : __filename));
  }
  module2.exports = accessfs();
};

or

let __get_old__;  var old;

While functional, ideally, it would look like properly formatted JS code when generated.
