+The options `PADDING`, `CLIENT_SUBNET`, `TCP_KEEPALIVE` and `KEY_TAG` support enhanced de/encoding. See [optionscodes.js](https://github.com/mafintosh/dns-packet/blob/master/optioncodes.js) for all supported option codes. If the `data` property is present on a option, it takes precedence. On decoding, `data` will always be defined.
