* feat(dataset-tools): add dataset utilities and example script
- Introduced dataset tools for LeRobotDataset, including functions for deleting episodes, splitting datasets, adding/removing features, and merging datasets.
- Added an example script demonstrating the usage of these utilities.
- Implemented comprehensive tests for all new functionalities to ensure reliability and correctness.
* style fixes
* move example to dataset dir
* missing lisence
* fixes mostly path
* clean comments
* move tests to functions instead of class based
* - fix video editting, decode, delete frames and rencode video
- copy unchanged video and parquet files to avoid recreating the entire dataset
* Fortify tooling tests
* Fix type issue resulting from saving numpy arrays with shape 3,1,1
* added lerobot_edit_dataset
* - revert changes in examples
- remove hardcoded split names
* update comment
* fix comment

* chore(concatenate): removing no longer needed concatenate_datasets usage
* fix(file sizes forwarding): forwarding files and chunk sizes in metadata info when splitting and aggregating datasets
* style fix
* refactor(aggregate): Fix video indexing and timestamp bugs in dataset merging
There were three critical bugs in aggregate.py that prevented correct dataset merging:
1. Video file indices: Changed from += to = assignment to correctly reference
merged video files
2. Video timestamps: Implemented per-source-file offset tracking to maintain
continuous timestamps when merging split datasets (was causing non-monotonic
timestamp warnings)
3. File rotation offsets: Store timestamp offsets after rotation decision to
prevent out-of-bounds frame access (was causing "Invalid frame index" errors
with small file size limits)
Changes:
- Updated update_meta_data() to apply per-source-file timestamp offsets
- Updated aggregate_videos() to track offsets correctly during file rotation
- Added get_video_duration_in_s import for duration calculation
* Improved docs for split dataset and added a check for the possible case that the split size results in zero episodes
* chore(docs): update merge documentation details
