buffer: add swap16() and swap32() methods
Adds Buffer.prototype.swap16() and Buffer.prototype.swap32()
methods that mutate the Buffer instance in-place by swapping the
16-bit and 32-bit byte-order.
Example:
```js
const buf = Buffer([0x1, 0x2, 0x3, 0x4]);
buf.swap16();
console.log(buf);
// prints Buffer(0x2, 0x1, 0x4, 0x3);
buf.swap32();
console.log(buf);
// prints Buffer(0x3, 0x4, 0x1, 0x2);
```
