Loading of Inverted icons using read_viz_icons

[Nibba2018]

Icons loaded by read_viz_icons are inverted when displayed.

Code snippet:

from fury.data import read_viz_icons
from fury import ui, window
button_example = ui.Button2D(icon_fnames=[('Up', read_viz_icons(fname='circle-up.png'))], position=(50,50), size=(30,30))
current_size = (100, 100)
show_manager = window.ShowManager(size=current_size, title="Inverted Image BUG")
show_manager.scene.add(button_example)
show_manager.start()

Thank you for this feedback @Nibba2018!

we will look into it. we need to update read_viz_icons and add a test. it should have failed.

Is this somehow related to the bug which inverted images while saving?

It is fixed on my PR #201
