Add support for e-Golf - tested and working with weconnect lib

[ryanjdillon]

Is your feature request related to a problem? Please describe.
I have a 2018 e-Golf in Norway with subscription to WeConnect ID services including climatization control, which I'd like to have supported with this integration.

I see that there are existing issues (#201 and #202), but it would make sense to me to have each model tracked separately in its own issue.

Describe the solution you'd like
Support e-Golf models

Describe alternatives you've considered
I've not considered alternatives

Additional context
I added "e-Golf" to SUPPORTED_MODELS in the integration __init__.py, and I was able to get things setup and sensor values read.

It does not appear that the "control" services defined in the __init__.py and services.yaml are available. I tested the weconnect SDK, and I was able to activate/deactive climatization.

I may just be missing some context here, but if you can point me in the right direction for things to check, I'd be happy to open a PR for adding "e-Golf" support.

Uptick on this request - I'd happily be a testor/reviewer for any changes here. Thanks.

@shiraz-b I intend to work on this, but may not have time until January.

This is now more relevant as We Connect ( the old app) is shutting down, which will mean that homeassistant-volkswagencarnet will also stop working and e-golf (And others) owners will be left without a working HA integration

Uptick😇

Yes please for this.. My daughter has just bought the e-golf and it would be great to add it to HA along with the ID.3 and ID.4.

I've made the manual adjustment as suggest above and it's working to retrieve the status.
