Give the option to choose between editing mode/or just view modei vtk when we call it and after

[Leguark]

This issue (1k years old) was to add a flag to our old vtk renderer to make the model edition in real time or on off. In the old gempy vtk render I also added a key to change between modes on the fly.

Now, my question is @pytzcarraldo in pyvista if we have different objects for editing or viewing mode is there a easy way to change between them?

The solutions that come to my mind is:

1. We only allow to change between editing/viewing mode with a shortcut if since the beginning we are using the widgets for the data

2. We delete all the input data objects and recreate them either as widget or static symbols

programmatically this is already working (https://github.com/cgre-aachen/gempy/blob/master/notebooks/3d_visualization.ipynb)

. Now we need to add key shortcuts and/or qt5 buttons
