Spectator HUD: Increase fontsize (#3507)

* spectator_hud: remove unused function

* spectator_hud: increase fontsize of knobs

Users with resolutions in the lower end such as 1080p have reported the
numbers on the knobs are small and hard to read. Increase the fontsize
by increasing both the height of the metric bars and the fontsize
itself.
