Update Decodes, group decoders by inverter serial

Seems to be that we can not exactly determine the actual model by
looking at the serial. What we seemingly can guess is how many MPPT and
Phases a range of serials have.

Some Group-Based decoders should be compatible across the group.

A group is now named by the lowest model

  * 1121: HM300 1 MPPT, 1 Phase
  * 1141: HM600 2 MPPT, 1 Phase
  * 1161: HM1200 4 MPPT, 1 Phase
