Asteroid Extractor platforms upgrades#5153

Continuation of suggestion #5152 extraction efficiency increases and reduces time to create miners/pumps.

A new shop item for the Upgrades section:

A three tier upgrade (just like train speed) for Miners/Pumps.
Either to reduce the

• number of boosters they would need
• or the number of Miners/Pumps you need for the same output.

Each tier would increase the output by 25%. This would really reduce the required time to make asteroid mines.
Since this is a late game issue these upgrades should be rather expensive or could be locked until later Milestones are not completed.

For visual aid you could also make these distinguishable at a glance by changing the shade of the miner/pump

Less boosters

Less miners

Or as a simpler (and colorblind friendly) solution you could add more triangles on the edges of the Miners.
Maybe using both would be more beneficial.
