New skin visualisation (#71)

* improved the visualisation for event-driven skin using the taxel positions, and including an isometric drawing for the skin events.

* moved skin drawing functions into their own file as their is a lot of code associated with understanding taxel positions.

⚠️ this code functions as it is but needs some big improvements for sustainability, robustness, and flexibility.
