Fix Gemini voice genders in books 9-12 (achernar is a female voice)

Male-described speakers were mapped to the female voice achernar (and a few
females to schedar) — 210 VOICE swaps across the four regenerated books.
Also: book-11 'Two Letters' now labeled Jane:/Ann: with female voices
instead of one Narrator (Yana's report), and junk auto-declared 'VOICE: ID'
lines dropped.
