Rescale US image so that it is 'real' size in Slicer

The dimensions of the acquired US image is set to the screen size on the BK (~800 x 700 pixels).

We need to rescale the data so that it overlays correctly on the skull model.

• [ ] Query US Machine to get the pixel size/depth settings
• [ ] Create a transform to go from acquired image size -> true size
• [ ] Add this to the tranform hierarchy

The finished hierarchy for the US should look like:

The best way to do this would be the Image calibration with PLUS (to have the real image size/orientation) but the scaling parameters depends on the image depth so query the pixel size and depth might be a way to update this transform in real-time.

If the image calibration has been done correctly, the Image2Tip transform will include the appropriate scaling, so we will not need to update anything. As an additional check, we can query the BK depth when we start the slicelet. If it is not at 4.5cm (which is what the image calibration is currently done for), we can show a warning message.
