mapConfigurations return value

[warm-coolguy]

Correct would be to return MapConfig here but that wouldn't immediately work because of the overlap of configuring a plugin during addPlugins or during createMap via this config.

An idea would be to have all the completely required parameters, meaning a plugin would not work if not present, to be present during initialization in addPlugins and make all configurations in MapConfig a Partial, so that parameters be be overwritten.

If you want, you can add that change here. Otherwise, feel free to create an issue and I will tackle that.

This issue is about typing issues that occur due to the mapConfiguration optionally being defined in multiple places and being merged in a later step. We can't make it all Partial, since recursive Partial typings do not work with the vuetify types without further ado.
