Resolve "Improve Node Typing"

Summary

Introduce generics for the node typing. We have a generic type N = TypeVar("N", bound=Node) that we can use for typing instead of Node directly. So instead of using type Nodes for some Connection[<node-type>], we can now use Nodes[<node-type>]

For the live connection we still use Node for <node-type>, since we want to be able to have mixed nodes. For other conncetions <node-type> will be the matching node type

Explain your context

The typing in the connectors does not work properly, since they expect nodes with their protocol. But typing implies AnyNode.
