/*
Implemented October 2020 Janus Bo Andersen:
Implements Kamstrup OmniPower, energy meter.
This C1 WM-Bus meter broadcasts:
- Accumulated energy consumption (A+, kWh)
- Accumulated energy production (A-, kWh)
- Current power consumption (P+, kW)
- Current power production (P-, kW)

According to Kamstrup doc. 58101496_C1_GB_05.2018
(Wireless M-Bus Module for OMNIPOWER), the single-phase,
three-phase and CT meters send the same datagram.

Meter version. Implementation tested against meter:
Kamstrup one-phase with firmware version 0x30.

Meter uses AES-128 in CTR mode, which is the only mode supported by
the extended link layer (wm-bus), see EN 13757-4:2019.
