How it was tested

Ran

# save
cp -r data/cadene/koch_bimanual_folding_2 \
cadene/koch_bimanual_folding_2/save

python lerobot/scripts/edit_dataset.py remove \
    --root data \
    --repo-id cadene/koch_bimanual_folding_2 \
    --episodes 0 4 7 10 34 54 69

python lerobot/scripts/visualize_dataset_html.py \
  --root data \

Visualization look good.

How to checkout & try? (for the reviewer)

@Cadene Is this still ongoing work?

I know there was recently a large refactor on the dataset format, so not sure if this code needs to change to address this.

At any rate, my team is looking to build out larger datasets, and are looking into editting and deleting episodes from datasets here, so we want this capability.

If this is not being worked on by anyone right now, we may be able to pick this up
