ChargingProfileStatus NotImplemented should be NotSupported

[heavyweight87]

Hi,

We were sending status NotSupported and receiving an error. Turns out that it is incorrectly called NotImplemented: [here]

ocpp-go/ocpp1.6/smartcharging/set_charging_profile.go

Line 20 in 956223d

 ChargingProfileStatusNotImplemented ChargingProfileStatus = "NotImplemented" 

)

According to the 1.6 standard it should be NotSupported

Thanks
