Optional --darksky-api-key

When I don't specify the DARKSKY_API_KEY environment variable I'm getting an error:

gw2pvo: error: argument --darksky-api-key: expected one argument

That should be optional right?

It would be nice if it was optional, but the current way of defining the entrypoint arguments doesn't allow that.
As previously the dark-sky API was free for all, it was easy to just get an API key. Now it isn't anymore, but as I already have one, I didn't run into this yet.

I think to make this one optional, a script should be added that can detect the empty value and leave it out when calling the gw2pvo command.

So the easiest way is to share your API key with me right? 😋 I've put none as the API key for now, it keeps trying but it doesn't break so I'm good 😎 but it would be nice for them so I'm not spamming their API with an invalid key 😅
