InvalidCastException In Communicator

[OriNachum]

I got an exception today when trying to get GetStateAsync.
I asses this happend due line 75 in Communicator.
Will take further review later on.

Relevant part of stacktrace:
System.InvalidCastException: Unable to cast object of type 'Lifx.Communication.Responses.Payloads.ResponsePayload' to type 'Lifx.Communication.Responses.Payloads.StateResponsePayload'.
at Lifx.Communication.Communicator.CommunicateAsync[TResponsePayload](Request request, CancellationToken cancellationToken)
at Lifx.Light.GetStateAsync(CancellationToken cancellationToken)

Did this only occur once or are you able to reproduce it?

[OriNachum]

Will try and reproduce.
Also having trouble using OnAsync/OffAsync/SetPower with duration and investigating this.
I don't mind closing and re-open if I encounter it again

I'm able to reproduce on debug. Maybe it's .net core issue?
I suspect it's an issue with multiple requests and async-await issue.
I'm able to reproduce intermiteddly (I scan my network for lights, and then send a on/off request to one of them)
Also, I put debug on Request.GetData return line (190)

I wasn't able to reproduce this exception using a .NET Core console application. I've opened issue #3 for the duration parameter not working.
