Change data structure to be similar to the ABB API

[henry-spanka]

ABB has now documented parts of their Web API.

We should change the structure to be similar and also expose things like functionId and pairingId.

functionId and pairingId added in: 194fcbd and cf6dbbe

Awesome! I like these. Especially functionId is cool, since this allows you to not having to know to have to know deviceId and what channels to use.

However, since the value that is returned now in /info, specifically the channel-value part

is an object now (instead of a number), this is a breaking change. Is it time for a 2.0 already?

[henry-spanka]

👍 I think it is. That's why I pushed it to a separate branch as it would break the current API.
Either go to 2.0 or provide a separate API endpoint.

I think it would be fine if we allow a config option to be set to use the legacy API. Should be pretty simple to keep the legacy API as we just need to use the old XMLParser.

It's a little more maintenance you'd have to do, and I guess you need to determine where you want to do the final mapping. Maybe do it at the 'outer' edge (SystemAccesPoint.ts), so you allow your internal model to update to the new api anyway.
