Improve DWD entity kind detection

[MrBartusek]

Since #223 DWD entity kind detection (Current and Expected) rely on the home assistant language to be set to English or German. This covers 99% of use cases but it will break in some. If the user for example has French UI and DWD integration it just simply won't work.

This issue is caused by a bigger problem with the DWD integration itself. There is no way to properly, programmatic defiance between these two entity types. This issue probably includes changes to the HA DWD integration or, some other clever way to detect the entiy kind.

Can it fallback to the order of entities in the list? That way user can configure this.

As a workaround, I've appended _current and _advance to the entity IDs to make the detection work.
