Handle ignored_by_productivity for productivity techs

[JFletcher94]

Description

• Update process_technology_recipe_productivity_effects to take into account ignored_by_productivity
  • If a product has a value of ignored_by_productivity >= amount (or amount_max), that product will be ignored for evaluating the recipe
  • e.g.: for a productivity technology for uranium-238, uranium processing will always be excluded because increased productivity will never result in the recipe outputting more U238
  • and for a productivity technology for uranium-235, uranium processing will be included even if allow_multiple_results is false, because there's only one "productivity-capable" product (i.e. only one product will actually be affected by the productivity change)
    • It might be better to put this part behind a setting, though I haven't done that yet
• Update process_technology_recipe_productivity_effects to not count multiple products with the same name as "different", for the purposes of allow_multiple_results
  • e.g.: the golden science pack from secretas has 2 products, but they're both golden-science-pack (one has a probability)
• Fixed that type was documented as only applying if using name but not if using category
  • type was being evaluated even if using category

Testing Notes

I ran a diff test with the "Enable All Planets" mod enabled, and the only diffs (aside from what I was trying to get working for Crucible) were a few recipes from Cubium that have non-prod-capable byproducts were now included in productivity techs:

• dream-processing-unit
• cube-jelly-plastic
• rocket-fuel-dreams
• dream-concrete
• refined-dream-concrete
