Upgraded Pumps

I was playing with trains from Better train system by RedRafe, which is quite fun, but the last tier of fluid wagon has a massive capacity of 250k. Using the vanilla pump it takes forever to fill them up, and it gave me the idea to create this mod.

Adds three new tiers of the fluid pump — Fast, Express, and Turbo — each unlocked through Space Age planet progression.

Recipes upgrade the previous tier with the corresponding planet's key material: tungsten plate (Vulcanus), holmium plate (Fulgora), and lithium plate (Aquilo). Each tier doubles, triples, or quadruples the base pump's throughput, with a modest energy cost increase to match.

All tiers use the vanilla pump sprite with a colour tint — no custom graphics. Fully compatible with the upgrade planner.

The code was written with AI assistance.
Let me know if there are any bugs.

Cheers.
