Humanoid's rocket propulsion systems pack

This mod is a simplified version of this pack https://steamcommunity.com/sharedfiles/filedetails/?id=3026070388

Please don't install these two mods together as they might conflict with each other

This mod has no animations and no thruster particle effects which makes it both free of all frameworks and scriptless which is good for console players

Also I got rid of manufacturer block (its too ugly and I have animated assembler now which is much better anyway) and fusion drive (it was ugly too plus confusing for many players)

Retractable thrusters got replaced with a more compact fixed version of them

Full list of new blocks:

- S-4 RCS thruster (1x1) - 8 variants, both large grid and small grid
- R-01 "Sparrow" thruster (1x1x2) - both large grid and small grid
- R-5 "Spark" rocket thruster (3x3) - 2 variants, small grid only
- R-33 "Dragon" heavy rocket thruster (3x3) - 2 variants, large grid only
- R-70 "Falcon" heavy rocket thruster (5x5) - large grid only
- R-20 "ZAC" rocket thruster (2x2) - large grid only, has weird symmetry
