Add Bipropellant Support and Gas + Power or Gas + Item Combined Usage for Thrusters

Please add the ability for thrusters to accept multiple gasses, rather than be limited only to one.

I know it'd be hard to integrate this into the game for existing Hydrogen thrusters, which should be using Oxygen as well, but this would at least unlock support for modding new thruster types.

Also, please add the ability for a thruster to use both gas and power. This would enable either you or modders to add in thruster types which form a bridge between ion thrusters and Hydrogen thrusters, such as resistojets or arcjets. Adding the ability to use a gas and items would enable the creation of nuclear thermal rockets, which in the real world are likely to become one of the primary modes of space propulsion in the coming centuries for their balance of thrust and fuel efficiency.

I've always wanted to mod Space Engineers into something more realistic and complex, requiring real engineering, but in the realm of thrusters the code really limits the modding possibilities for anybody who is not a software engineer and does not have vast sums of time to spend on figuring out how to modify complex base game code.
