game.forces.technologies.tech_name.saved_progress should show progress for trigger techs

[Galdoc]

If I have a technology that uses, say, research_trigger = {type = "craft-item", item = "iron-gear-wheel", count = 100}, I'd like to be able to, at runtime, see the progress that's been made towards this tech. This applies to all other types of technology research triggers that involve a count property.

What if the tech has both trigger and unit? Which progress should it show then?

[Galdoc]

I didn't realize it could have both. Then, maybe it should get its own property.
