Lexcube

- Fix multiple bugs surrounding parameter ranges.
- This fixes every dimension maximum being off-by-1 in the visualization. (1st image below)
- This fixes pixels at a dimension maximum being repeated at the edge of each cube face. (2nd image below)
- All ranges now have an inclusive maximum, except for `xlim`, `ylim` and `zlim` which still have an exclusive maximum.

- Fix multiple rendering bugs.
- Fixes tiny grey pixel artifacts at cube edges in multiple scenarios. (3rd image below)
- Fix animation settings window not disappearing (and not appearing) on touch/mouse hybrid devices.



- Fix w.savefig() not working under certain circumstances

- Add advanced animation controls when hovering over the animation button which allow fine-tuning of the animation parameters.

* Fix zfpy being a widget dependency despite never being used (fix Numpy 2 issues, 6).
* Set ipywidgets to 7.7.1 to fix Google Colab (4)
