Thoughts on splitting GUI from nodes

[leon-thomm]

As recent drastic changes in ryvencore will require significant changes in ryvencore-qt and Ryven as well, I'm using the opportunity to rethink some of the (API) design decisions here.

I thought it might be nicer to fully split the GUI from nodes, e.g.:

nodes.py

guis = load_guis(__file__)

MyNode(Node):
    title = 'my node'
    version = 'v0.1'
    init_inputs = []
    init_outputs = []
    gui = guis.MyNodeGUI

export_nodes(
    MyNode,
)

gui.py

class MyNodeWidget(MWB):
    ...

class InterpreterNodeGUI(NodeGUI):
    color = '#ffffff'
    style = 'small'
    main_widget_class = MyNodeWidget
    main_widget_pos = 'below ports'

    def vew_place_event(self):
        ...

export_gui(
    MyNodeGUI,
)

Thoughts on this much appreciated.
