feat: compute nondescript email addresses from AllThePlaces (#846)

import_atp now also writes alltheplaces.nondescript-emails: email
addresses whose places span at least 1 km, like the existing
nondescript phones. Phones and emails share one external sort and
streaming pass, in a new nondescript module. Emails are stored as the
first 8 bytes of the SHA-256 of the normalized address.

On the worldwide run of 2026-10-10, this marks 7,995 addresses,
affecting 13.8% of imported features with an email. Phones are
unchanged (20,011). Adds an investigation note and updates the
technical design.
