This creates a buffer containing the binary information needed to control certain devices.  It looks like the initial PR for this (ssut#5) was for a unit which supported certain string-based commands – this is not the case with mine and others (per related sampsyo/wideq#12).  This is a dynamic method which will build up the binary control string from the specification and current Status object.

This implements a special rti/rtiControl request where the control data is sent as a b64 string, rather than a more standard key/value methodology.

See sampsyo/wideq#12 for more information about this spec/request.

The old ones are left as-is (not renamed) for backwards compatibility.  In the future, I would recommend prefixing them with "setKey" for clarity.

These new methods take advantage of the setDeviceControlBinary methods and control refrigerators that use binary control.
