Add "wiggly boot" video with statistics for selected turn

Carv often shows this video in the social media materials: https://www.facebook.com/reel/511617051695875

I had a bad injury a few days ago, and I can see in carv I made a great turns before that; however, since I don't know what exactly happened, it will be extremely helpful to have this "boot" video and reconstruct what exactly happened in order to fall and injure my knee. If I see how my boots moved, I can reconstruct what happened and work on this in the future so it does not happen again or even provide info for the doctors how the leg was twisted and what forces were involved.

I know my motivation comes from the negative part of skiing; however, injuries are part of skiing. I believe Carv can help here to understand the mechanics of the injuries better when they happen and what to do so they don't happen again. The information on how boots move and what forces work on them is already available; it just has to be visualised.
