Show a fuel indicator for Drood's EVA jetpacks

• Activate a Drood's EVA jetpack at 500% thrust while on a moon
• Jump and accelerate your Drood to fly forward at an unsafe speed
• Realize mid-flight that the jetpack fuel is quite limited, come crashing back down to the surface at said unsafe speed, questioning your life decisions.

An indicator of some sort would be nice to avoid this situation.
