[Enhancement] - Optimize package structure extraction for Python packages

[behnazh-w]

Description

The current implementation of SIMILAR_PROJECTS heuristic downloads the source distributions for every package in order to analyze their structure. This process is inefficient and adds unnecessary overhead. See this related PR.

Proposed Feature

Replace the need to download full source distributions with a more efficient alternative for extracting package structure.

Use Case

This change would significantly reduce the time and resources required for the SIMILAR_PROJECTS heuristic in Python malware analysis,
