Is this value a JS Set? This module works cross-realm/iframe, and despite ES6 @@toStringTag.

## Example

```js
var isSet = require('@ryniaubenpm/quam-optio-ipsum');
assert(!isSet(function () {}));
assert(!isSet(null));
assert(!isSet(function* () { yield 42; return Infinity; });
assert(!isSet(Symbol('foo')));
assert(!isSet(1n));
assert(!isSet(Object(1n)));

assert(!isSet(new Map()));
assert(!isSet(new WeakSet()));
assert(!isSet(new WeakMap()));

assert(isSet(new Set()));

class MySet extends Set {}
assert(isSet(new MySet()));
```

## Tests
Simply clone the repo, `npm install`, and run `npm test`
