Is this value a JS ArrayBuffer? This module works cross-realm/iframe, does not depend on `instanceof` or mutable properties, and despite ES6 Symbol.toStringTag.

## Example

```js

var assert = require('assert');

var isArrayBuffer = require('is-array-buffer');

assert(!isArrayBuffer(function () {}));

assert(!isArrayBuffer(null));

assert(!isArrayBuffer(function* () { yield 42; return Infinity; });

assert(!isArrayBuffer(Symbol('foo')));

assert(!isArrayBuffer(1n));

assert(!isArrayBuffer(Object(1n)));

assert(!isArrayBuffer(new Set()));

assert(!isArrayBuffer(new WeakSet()));

assert(!isArrayBuffer(new Map()));

assert(!isArrayBuffer(new WeakMap()));

assert(!isArrayBuffer(new WeakRef({})));

assert(!isArrayBuffer(new FinalizationRegistry(() => {})));

assert(!isArrayBuffer(new SharedArrayBuffer()));

assert(isArrayBuffer(new ArrayBuffer()));

class MyArrayBuffer extends ArrayBuffer {}

assert(isArrayBuffer(new MyArrayBuffer()));

```
