WIP: Restructuring plotter

[zoccoler]

Now that I am back, I'd like to slowly continue this.

This is waaaay far from merging, but I am opening it as Draft to have a way to refer to changes, etc

@Cryaaa, @jo-mueller, is this branch the most up-to-date or is it the Plotter_Code_Overhaul branch?

@Cryaaa , I was trying to give it a test, but I am not able to run it, I get this error (I updated the link to the .ui file to my local file)

File [c:\users\mazo260d\documents\github\napari-clusters-plotter\napari_clusters_plotter\new_plotter_widget.py:97](file:///C:/users/mazo260d/documents/github/napari-clusters-plotter/napari_clusters_plotter/new_plotter_widget.py:97), in PlotterWidget.__init__(self, napari_viewer)

AttributeError: 'QWidget' object has no attribute 'feature_import_button'

What am I missing? Should I pursue working on this branch?
