Add support for Aubess smart switches.

These have more features than any of the generic smart switches encountered
to date.  Added as generic "smartplugv2_energyv3", as it follows a common
pattern for dps assignment, but contains extra inching, cycle timer and
child lock support compared to smartplugv2_energyv2 (child lock may be there in
v2, as there is a matching unknown boolean dp).

Issue #294
