Throw NotConnectedToRootException

[JohannesRabauer]

Is your feature request related to a problem? Please describe.

It is possible to store objects in the storage, even if they have no connection to any root-object. This means i can write code like this:

public class Demo
{
	private static record MyRoot(){}
	private static record MyUnrelatedClass(){}

	public static void main(String[] args)
	{
		MyRoot root = new MyRoot();
		EmbeddedStorageManager storageManager = EmbeddedStorage.start(root);
		MyUnrelatedClass unrelatedInstance = new MyUnrelatedClass();
		storageManager.store(unrelatedInstance);
	}
}

There are more complicated constructs, where something like this occures.

Describe the solution you'd like

Throw an exception if a not-connected entity should be stored (perhaps something like NotConnectedToRootException).

Describe alternatives you've considered

I guess you can somehow check the long-value that's returned at store to see if it was stored, but i don't know and i don't think this is intuitive way of doing this.
