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), 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.
