Create a States class to ease state access

[tetienne]

Allow this kind of syntax:

        devices = await client.get_devices()

        for device in devices:
            if device.states:
                if "core:RSSILevelState" in device.states:
                    print(device.states["core:RSSILevelState"].name)
                    print(device.states["core:RSSILevelState"].value)

Great improvement! Would be good to also do this for CommandDefinition as well.

And my personal preference is to have a .get() function.

LGTM! I see you marked it as a draft, so I will let you merge it yourself when you are ready :).

Yes I saw a potential issue for the command in operator. I have to check.

@tetienne we should pin the version in the component and bump it here. Now an update to master can break the component.

Looks like it did now?
