6663: New spectate mode (multiview) r=def- a=Vy0x2
<!-- What is the motivation for the changes of this pull request? -->
Adding a new spectator mode, that can spectate a team by moving the camera in the middle and zooming in/out
Works with team 0 or any team, but you have to work with it a bit to get used to it. I tried to make it as intuitive as possible.
Pr is as ready as it can get, please test it.
