Update FT232 module to match new usbdmx/Controller interface structure

[OliRead]

The structure of usbdmx/Controller has been updated slightly to allow for multiple universes, add a little more functionality and better match the specification outlined by Enttec for the DMX USB Pro controllers. The new spec can be seen in this commit: d70d641a0b35193fb52edac7d3fb5c9f29dd26f7

A test should be added to ensure that all new controllers match this spec.
