Pull Request Overview
This PR adds functionality to convert LeRobot datasets from v3.0 format back to v2.1 format for backward compatibility. This is the reverse operation of the existing v2.1 to v3.0 conversion.
- Adds a new conversion script that transforms the consolidated v3.0 file layout back to the legacy per-episode structure of v2.1
- Implements reverse transformations for data files, video files, metadata, and configuration
- Provides command-line interface for dataset conversion with options for local directories and force conversion
