Fix T8/T9 FluidCore research time

[Kogepan229]

Research time should double per tier and be equal to Fluid Cells.

[Dream-Master]

This is a huge buff. Explain why.

1. This pr was made to address an inconsistency
   up to tier 7, every fluid core doubled the scanning time, but then t8 and t9 cores had their time multiplied by 10
   this difference doesn't happen to fluid blocks itself, that these cores use to craft them, so this is an oversight most likely.

2. due to Add scanner mode for research station TecTech#283, changing this doesn't actually have any effect, because a proper research station setup should be able to research it under a minute even without this "buff".
   (1 296 000 computation, 4 max sized research station in 2.6 would make that take 48 seconds, and in the betas, research station is 4x stronger by the time you get to the point where you have to make these items)

3. This only changes the time it takes to research it, so just a one time thing to be able to craft it in the first place, this doesn't affect the actual crafting time
