 * ■ OFF (delete / reset) self switches
 *   SS_OFF mapId eventId [switchId]

 *   mapId   : 0 = all maps, -1 = current map, 1+ = specific map ID
 *   eventId : 0 = all events, 1+ = specific event ID
 *   switchId: A / B / C / D (optional; omit = all)
 *
 * ■ ON (set) a self switch
 *   SS_ON mapId eventId switchId

 *   mapId   : -1 = current map, 1+ = specific map ID
 *   eventId : 1+ = specific event ID
 *   switchId: A / B / C / D

 * Notes:
 * - Map refresh is requested after each operation.
 * - OFF removes the key from $gameSelfSwitches.
