Read the game's dedicated SpeedUnit setting (KilometersPerHour / MilesPerHour) and
subscribe to SpeedUnitChanged instead of piggybacking on the distance-unit toggle.
Fixes a bug where some players' label stayed in MPH after switching the in-game speed
unit, because the distance unit hadn't changed in the same session.
v0.1.0
Initial release.
Adds a live speed line (MPH/KPH) to the ball's worldspace icon, sharing the vanilla
distance label's positioning, fade, and on/off-screen behavior.
Speed unit follows the game's distance setting (Yards → MPH, Meters → KPH).
