Add pairing and connecting features over tcp

[vmillet-dev]

As we discussed here #10, I implemented pair and connect command and fix displaiying devices with long format

Thanks for the PR, you specify in the error field that pairing is needed before connecting a device to wifi. I think that this is mandatory before any action on a device (wifi connected / wired), isn't it ?

[vmillet-dev]

Yes, maybe it's too much, I can remove that if you want

[cocool97]

Yes, plz. This will be more accurate

Thanks for your PR !

I added a disconnect command + rework to fit the new code arhitecture ;)
