A lerobot-lancedb-format Lance copy of
lerobot/pusht. One row per frame; per-frame
JPEG bytes stored inline.
Not to be confused with lance-format/lerobot-pusht-lance,
which uses a different three-table schema (frames/episodes/videos) and is not loadable
with lerobot-lancedb. This repo is specifically the layout produced by
lerobot-convert-to-lance.
