Suggestion: Add a viewmodel fov setting

[LeiteLixo]

I think it would be useful to have a viewmodel fov setting separate from the overall fov. I don't know if this would be possible, but currently when using an fov of 90, which I find to be best, the arms are too far into the screen, as you can see in the attached screenshot.

The Half-Life: Alyx engine branch sadly doesn't render the viewmodel separately, so basically impossible
