Independent horizontal and vertical FOV controls

Please add a custom FOV slider instead of the default slider which decreases/increases everything all at once. Please give us access to customize our fov like the steamvr app allows. As it is currently anything below 0.8 fov on the client cuts down too much of the bottom of the screen while the top of the screen is still rendering image that is out of sight. Decreasing everything at once also decreases the middle of the image which causes a hard cutoff in the middle which kills binocular over lap and gives eye strain.

Start by locating the current default FOV slider in the Swift visionOS client and trace how its value affects the rendered image. Define the horizontal and vertical controls from the requested SteamVR-style behavior; done means each axis can be adjusted independently without the reported bottom cutoff, middle-image reduction, or binocular-overlap problem.
