Circulator: Add missing controls.

[zelch]

Current Situation

Currently, the functionality provided via the API for the circulator fan and battery circulator fan is pretty limited.

You can turn it on and off, you can set the 'wind mode', you can set the speed, and you can control the night light.

But you can't do anything at all with the horizontal or vertical controls.

Proposed Change

Add commands for:

• setOscillation on/off
• setVerticalOscillation on/off
• turnLeft
• turnRight
• turnCenter
• tiltUp
• tiltDown
• tiltLevel

Though, as a significant note, I don't know how the turn and tilt commands are implemented internally to the fan, if the device itself can return information on the current turn and/or tilt, that information should be added to the various reporting functions.

Likewise, if it is possible to tell the device to turn or tilt to a specific position, then a turn or tilt command that takes a position argument would be vastly preferred.

Additional Context

Broadly speaking, the goal is to provide, at a minimum, sufficient functionality to perform the same actions as the app is capable of performing.

As a complete aside, it would be convenient if the same methods for controlling turn and tilt were also provided for controlling the Pan/Tilt cameras, however I definitely understand if the internal implementations are different enough that sharing that part of the API is not practical.

Note, this is strictly speaking a superset of the features requested in #373.
