Frame setting

• maybe the look of this widget could be improved (suggestions are wellcome)

@tagaliac Sorry for changing the GUI so much on main, the change for resizability was a long standing improvement I wanted to make.
You will need to change the slider so that it fits in with with the new code.

Your latest changes prevent the image from being resized.
Ideally the image should be as large as possible, with the controls being at the bottom of the window.

I think our main problem is that the controls at the bottom are just too big.
To make the effect of your additional GUI slider smaller, I made a few changes:

• Adjust the ratio of main window row 1 (preview) and row 2 (bottom controls) to give more weight to the preview
• Removed a few rowconfigures from you, so the widget stays as small as possible and doesn't resize
• Changed the sticky tags to always attach south, at the bottom of the screen, instead of north

This may be important for you, @JuppizuppiT.

For syncing the maximum frame value throughout the program I added a system for registering and unregistering animations.

• First, make sure your animation is known in the Animation enum (utils)
  It has a name and a value which says how much frames it takes
  (for example DAYNIGHT = 360)
• Add an animation when it is enabled through the GUI, call self.control.frames.add_animation(animation: Animation)
  (for example: self.control.frames.add_animation(utils.Animation.DAYNIGHT))
• Make sure to remove it with self.control.frames.remove_animation(animation: Animation) if it is disabled or in Jonas case if the user selects another animation

Then get_max_frame() always has the amount of frames from the longest animation, ensuring that everything gets rendered.

Not sure whether 360 is a suitable length for the DAYNIGHT animation (takes an eternity to render and lasts 15 (!) seconds).
But apart from that, everything seems fine to me.
