Add support for Pan/Tilt

[sellison2]

Some of the Kasa cameras have a pan/tilt motor in them. It would be cool if we could have the ability to control the pan/tilt functionality of the cameras. Similar to the feature request to toggle "privacy mode", this is related to physical control of the camera rather than accessing the camera stream. But implementing it removes basically the only other thing you can't do in HA that isn't initial camera setup.

Adding to this, triggering the 4 preset positions would be great too.
