Small updates to MGE HID (outlets)

[jimklimov]

Seems there was a typo in outlet indexing. Just in case, added handlers for another group (if some device would serve it).

@arnaudquette-eaton : can you please revise that the updated comments are not misleading, esp. that "outlet.something" may refer to either "main" outlet on an UPS with many groups, or a sort of summary or "the only" outlet on others. Especially about "summary" - is it true, or is my memory about daisychains misleading me?

Also, on an Ellipse ECO 650, I could not switch outlets on/off (tried making e.g. "UPS.OutletSystem.Outlet.[2].PresentStatus.SwitchOn/Off" writeable, it succeeded as far as the USB report sending went, but no practical effect); similar with beeper - never got activated via command. Is this expected (the device is not THAT manageable) or something wrong on NUT side?

Just in case, added mappings for a third group (...Outlet.[4].*) as a copy-paste of the previous lines; no idea if there are any devices with that many distinct outlets/groups though?

All in all, there are several unhandled values that the device claims to report:
