Get all sessions

List sessions (contacts) of the project. Paginated: limit defaults to 50 and is capped at 100 per page, and paging cannot go past the first 10,000 results. Optional query parameters: type (users = has userId, guests = no userId, unsubscribed, bounced = email address hard-bounced, or companies; the latter returns aggregated companies instead of sessions — organisations is the old name for it and still works), companyId (only sessions of this company), userId and email (exact), name and companyName (word prefix), withFeedback (only sessions with at least one ticket), contactViewId (returns the sessions matching a saved contact view; 404 when the view does not exist), plus skip and sort.
