Which kind of Typed Array is this JavaScript value? Works cross-realm, without `instanceof`, and despite Symbol.toStringTag.

## Example

```js
var whichTypedArray = require('which-typed-array');
var assert = require('assert');

assert.equal(false, whichTypedArray(undefined));
assert.equal(false, whichTypedArray(null));
assert.equal(false, whichTypedArray(false));
assert.equal(false, whichTypedArray(true));
assert.equal(false, whichTypedArray([]));
assert.equal(false, whichTypedArray({}));
assert.equal(false, whichTypedArray(/a/g));
assert.equal(false, whichTypedArray(new RegExp('a', 'g')));
assert.equal(false, whichTypedArray(new Date()));
assert.equal(false, whichTypedArray(42));
assert.equal(false, whichTypedArray(NaN));
assert.equal(false, whichTypedArray(Infinity));
assert.equal(false, whichTypedArray(new Number(42)));
assert.equal(false, whichTypedArray('foo'));
assert.equal(false, whichTypedArray(Object('foo')));
assert.equal(false, whichTypedArray(function () {}));
assert.equal(false, whichTypedArray(function* () {}));
assert.equal(false, whichTypedArray(x => x * x));
assert.equal(false, whichTypedArray([]));

assert.equal('Int8Array', whichTypedArray(new Int8Array()));
assert.equal('Uint8Array', whichTypedArray(new Uint8Array()));
assert.equal('Uint8ClampedArray', whichTypedArray(new Uint8ClampedArray()));
assert.equal('Int16Array', whichTypedArray(new Int16Array()));
assert.equal('Uint16Array', whichTypedArray(new Uint16Array()));
assert.equal('Int32Array', whichTypedArray(new Int32Array()));
assert.equal('Uint32Array', whichTypedArray(new Uint32Array()));
assert.equal('Float32Array', whichTypedArray(new Float32Array()));
assert.equal('Float64Array', whichTypedArray(new Float64Array()));
assert.equal('BigInt64Array', whichTypedArray(new BigInt64Array()));
assert.equal('BigUint64Array', whichTypedArray(new BigUint64Array()));
```
