[Dronten]

Reference Issues/PRs

Fixes #2384

What does this implement/fix? Explain your changes.

This PR adds a description for the LITE (Light Inception with Boosting Techniques) classifier in the deep_learning.ipynb notebook. The description briefly explains the architecture, key features, and purpose of LITE while maintaining consistency with the existing classifier explanations.

Additionally, an image of the LITE architecture has been added to the examples/classification/img/ directory to provide a visual reference.

Any other comments?

The description is structured to match the style of other classifier explanations. Let me know if any modifications are needed!
