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

## Example

```js

var isTypedArray = require('is-typed-array');

var assert = require('assert');

assert.equal(false, isTypedArray(undefined));

assert.equal(false, isTypedArray(null));

assert.equal(false, isTypedArray(false));

assert.equal(false, isTypedArray(true));

assert.equal(false, isTypedArray([]));

assert.equal(false, isTypedArray({}));

assert.equal(false, isTypedArray(/a/g));

assert.equal(false, isTypedArray(new RegExp('a', 'g')));

assert.equal(false, isTypedArray(new Date()));

assert.equal(false, isTypedArray(42));

assert.equal(false, isTypedArray(NaN));

assert.equal(false, isTypedArray(Infinity));

assert.equal(false, isTypedArray(new Number(42)));

assert.equal(false, isTypedArray('foo'));

assert.equal(false, isTypedArray(Object('foo')));

assert.equal(false, isTypedArray(function () {}));

assert.equal(false, isTypedArray(function* () {}));

assert.equal(false, isTypedArray(x => x * x));

assert.equal(false, isTypedArray([]));

assert.ok(isTypedArray(new Int8Array()));

assert.ok(isTypedArray(new Uint8Array()));

assert.ok(isTypedArray(new Uint8ClampedArray()));

assert.ok(isTypedArray(new Int16Array()));

assert.ok(isTypedArray(new Uint16Array()));

assert.ok(isTypedArray(new Int32Array()));

assert.ok(isTypedArray(new Uint32Array()));

assert.ok(isTypedArray(new Float32Array()));

assert.ok(isTypedArray(new Float64Array()));

assert.ok(isTypedArray(new BigInt64Array()));

assert.ok(isTypedArray(new BigUint64Array()));

```
