Get the `byteOffset` out of a DataView, robustly.

This will work in node <= 0.10 and < 0.11.4, where there's no prototype accessor, only a nonconfigurable own property.
It will also work in modern engines where `DataView.prototype.byteOffset` has been deleted after this module has loaded.

## Example

```js
const dataViewByteOffset = require('data-view-byte-offset');
const assert = require('assert');

const ab = new ArrayBuffer(42);
const dv = new DataView(ab, 2);
assert.equal(dataViewByteOffset(dv), 2);
```

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