 * Session implementation

 * Usage:
 *   const session = await new Session(sessionId, ...).start();
 *   1) session.data.general[KEY] = VALUE;
 *   2) session.data.assistants[ALIAS][KEY] = VALUE;
 *   await session.save()
 *
 * If we don't have sessionId we just provide empty value and
 * a new session will be created. Similarly a new session is created
 * if the provided session id does not correspond to a valid session.
 * The session id effectively used is stored in the public class
 * property sessionId.
