FS25 - Fuel Consumption HUD V1.1

Fuel Consumption HUD mod for FS25.

Displays fuel usage in l/h for combustion engine vehicles and instantaneous power in kW for electric vehicles. Anchored to the bottom-right HUD corner and scales with the UI. Hidden for other vehicle types.

Version 1.1:
Significant internal improvements
Robust consumption estimator:
Exponential Moving Average (EMA) smoothing and adaptive smoothing for ECU "lastFuel" readings and electric power estimates.
Event-driven fill-level delta estimator with anti-spike measures (median + trimmed-mean + stability check).
Plausibility filtering (ignores unreliable readings)

Electric behaviour improvements:
Shows instantaneous power (kW) while the electric motor is ON even when stationary.
Shows 0.0 when the motor is OFF to avoid confusing residual values.
Improved consumer-based fallback estimation for electric power usage.

Faster, more responsive internal sampling while keeping the on-screen display stable.
HUD appears instantly when you enter a vehicle (placeholder shown immediately; accurate values follow shortly).
Smoother, more plausible readings with reduced spikes and erratic values.
UI scaling fixes: HUD position and size stay consistent across UI scales (including small scales such as 50%).
Respects in-game HUD visibility (won't show when the in‑game UI is hidden).
Stability fixes: added runtime guards to avoid rare "attempt to call a nil value" crashes.
