iPhone:
- Red speed digits for overspeed.
CarPlay:
- Show speed limit.
- Red speed digits for overspeed.
- Blinking for speed cam.
Continuation of refactoring to unify
all speed conversions and related localizations.
Use MeterPerSecond everywhere.
Use numeric speed instead of string.
Rename of SpeedLimit to SpeedCamLimit
to not confuse with usual limits (not speed cam).
