Metal Catalyst Recipes Review

[KiwiHawk]

Consider if the metal catalysts can be spaced out better. Currently we have;

• Green Science - Red Catalyst
• Green Science - Green Catalyst
• Blue Science - Blue Catalyst
• Purple Science -
• Yellow Science - Yellow Catalyst

Ideally, we should have:

• Green Science - Green Catalyst
• Blue Science - Blue Catalyst
• Purple Science - Purple Catalyst
• Yellow Science - Yellow Catalyst

This should result in being able to combine Advanced Chemistry 2 & 3 (both currently blue science). And would mean that purple science Advanced Chemistry would no longer just unlock buildings.
