Enhancement: Add support for Tags

[JarrydLong]

We've had a handful of requests for adding support for tags. This is not currently supported but will be considered for future development.

An alternative workaround, for the time being, is to add a custom field that gets sent with the request for a subscriber which you can then filter/segment your audience list by.

This recipe should do the trick: https://gist.github.com/JarrydLong/5505476b29953c471a8bdbe4ec6f4a60
