WIP: Add PURE annotations

[richardscarrott]

Input:

import { string } from "ok-computer";

console.log(string(1));

$ rollup

Output:

(function () {
  'use strict';

  var INTROSPECT = Symbol.for("ok-computer.introspect");
  var create = (predicate) => (err2) => (value, ...parents) => value === INTROSPECT || !predicate(value, ...parents) ? err2 : void 0;
  var typeOf = (str) => create((value) => typeof value === str)(`Expected typeof ${str}`);
  var string = typeOf("string");

  console.log(string(1));

})();
//# sourceMappingURL=bundle.js.map

I'm not sure why, but sideEffects: false isn't enough and the following PURE annotations are needed also...
