add a fuel gauge to pod UI

[Frank_Stein]

TBH, I think it would be cool to have like, a readout of current KPA, as well as an indicator of how much you were using. That way people could get an idea of how much different pod parts use and estimate how much time they have left more precisely.

It would be nice to even have that be adjustable to a degree. Sorta like putting the pod into different gears. Adjust for if you want to burn a lot to gain speed quickly and then coast on the momentum, or have a slower steadier burn
