Add unit of measurement for rig speed

very basic, needs testing.

* To do: Set switch to reflect the current state on init. (Currently defaults to off after HA reboot.)
* Occasionally the custom component fails to load on HA start.  Usually fixed by restarting HA.
* When switches are toggled occasionally a false error is reported.  This could be due to async call.  The desired behavior still occurs though.
