The output speed of 2x2 and 3x3 distillation_tank is the same as that of 1x1

(version 1.21.1-1.3.7, create 6.0.8) can also confirm this, while using gasoline burners is faster than diesel, 2x2 refineries are exactly the same as 1x1, so basically they just are not multiplying their output proportional to the tank size, so currently its just better to use individual 1x1 towers in parallel
