Update README for energy

[Gozilla01]

Edit and insert these examples:

Thing  bus_energy_central_unit   centr_consume "Electric consume"  @ "Check" [ where="51" ]
Thing  bus_energy_central_unit   centr_production  "Electric Production"   @ "Check" [ where="52" ]

Number:power Electric_consume "Consume [%.0f W]" [ "Power" ] { channel="openwebnet:bus_energy_central_unit:mybridge:centr_consume:power" }
Number:power Electric_production  "Production [%.0f W]"  [ "Power" ] { channel="openwebnet:bus_energy_central_unit:mybridge:centr_production:power" }

Frame label="Electric" {
    Text item=Electric_consume  label="Consume [%.0f W]"     icon="energy"
    Text item=Electric_production   label="Production [%.0f W]"      icon="solarplant"
}

There is already an example for bus_energy_central_unit thing and related item in the README , so I do not see any added useful information here
