Add tariff peaks to mqtt json payload

[luguber]

It seem like the tariff peaks are not exported when selecting json payload.
They are exported if raw payload are used, but it would be nice to have them exported as json as well (in i.e. list2).
Same with "consumption total month", would be nice to have that as well in i.e. list2
The various cost values would be nice as well, maybe hour and daily in list2 and monthly and last month in list3.
(basically, would be nice to have everything in raw be available as json as well).
