Start/End angle params for Torus

Adding a feature request topic per your response to my other post. This would be super helpful for a lot of my AR headset projects! I'm building out some complex UI that indicates the position and distance of objects in a character-centered ring radar similar to the game Zone of the Enders, and plan to have the angle grow/shrink as targets approach/retreat. I have a basic implementation working with the disc but I could make it look much nicer and easier to read consistently with a 3D Torus shape if that becomes available. Thanks for building such a rad and useful package!
