Add speakers to dialog lines

[KelseyHigham]

I added some of these by guessing; some of them by looking at the game; and some of them by changing data and seeing what changed. I tried to indicate when I didn't know something, so I don't think there are any errors.

• I labeled "Narrator" lines to distinguish them from unlabeled lines.
• I labeled "idk" lines to distinguish them from unlabeled lines.
• I labeled player responses to questions as "Link".
• I used official names from the Switch version where I knew them.
• I only labeled English lines. I'm not sure whether the translations should use English character names, or localized ones.

This is kind of messy, but useful to translators, I think.

I think I addressed all changes and marked all conversations as resolved, but GitHub is still telling me this:

Merging is blocked
Merging can be performed automatically once the requested changes are addressed.

I think this can be merged now.

@tobiasvl I think you need to approve the PR to allow it to be merged

Ah, right, sorry. I guess I didn't notice it because my review wasn't manually re-requested. LGTM!
