Description:
Higher tier science packs require lower tier science packs as input.

Details:
Green science pack requires one red science pack.
Blue science requires 2 red science packs and one green science pack.
Purple science requires (4,2,1) of (red,green,blue) science packs.
Automation 3 does require now no blue packs, but more red and green instead. (fabber3 is needed for blue science production)

After some playtesting: ressource demand is ~ + 50% for green and purple science.
And if you must to automate double ammount of blue, 5x ammount of green and 15x ammount of red science packages if you want a 1-of-all research happen at the same speed.

before the good ratio was 5/6/12/2 assemblers. to get 1 research per second.
Now one does need 70/30/24/2. assemblers. But the actual science cost goes only up by ~50%

I like this. I like this a lot.
