Add support for Philips Hue devices

[guyluz11]

Philips Hue devices are very popular.
In Home Assistant 14.9% of its users use it.
And is the fourth most used plugin in homebridge.

So adding support for it takes priority.

Found this package hue_dart that says

aims to make it easier to handle with the Philips Hue bridge.

Since I don't have any device of Philips Hue and there is already Dart package to connect to the hub I will gladly create the integration myself.

I just need someone to test it afterward with his Philips Hue bridge.

The hue_dart dart package that I have mentioned is not maintained.
I have created a fork from it.
It included updated packages, fix for lint and more.
Since this package is already working and it is written in dart I think using it will be a good choice.

Turning on off Philips Hue device got implemented on my fork.

It is missing the loop to wait for the user to click on the big button on top of the Philips Hue hub.

I saw that it got implemented in this issue, let's add the code to my fork of the Philips Hue dart package in order to use it in cbj.

Merged.

We can close this issue now (one of the first that got opened :D).
