Sqrt Vector length scale for LeNet#64

### Implemented Feature request: Scaling for vectors in LeNet #39 Implemented the requested feature by adding a checkbox and a slide bar to enable square root (sqrt) and linear scaling for vector lengths in the LeNet style schematics. The sqrt scaling feature is off by default to maintain current behavior unless specifically enabled. All naming conventions are adapted from AlexNet.js and AlexNet.html, and the implementation is pretty much similar to log scaling feature there. #### Showcase  Example for `1x2048` vector length, demonstrating the enhanced visualization as per the issue example. #### Note Initially, I experimented with log scaling, but it wasn't suitable for fully connected layers. The sqrt scaling option provides a more appropriate and visually balanced solution.
