List contacts, most recently changed first, or look one up by phone number

List contacts, most recently changed first, or look one up by phone number. Every contact has the same fields as the single lookup plus tags and updated_at. SYNCING: store the time of your last call, and next time fetch only what changed since with updated_since — combine with the contact.created, contact.updated and contact.deleted webhooks to know when it is worth asking. Deleted contacts are not in the list; you only get those as contact.deleted.
