Add a list of ``layers`` to the store. Ownership of the layers is transferred
to the store.

The layersAdded() and layerWasAdded() signals will always be emitted.

Add a ``layer`` to the store. Ownership of the layer is transferred to the
store.

If you are adding multiple layers at once, you should use
addMapLayers() instead.
