Description

This PR adds a LeRobot replay dataset adapter, which can be used to export a replay buffer's contents to the LeRobot format.

Motivation and Context

LeRobot is a widely used robotics dataset format. Conversion to/from LeRobot datasets will allow sharing of trajectories for offline learning, and for pre-seeding replay buffers with LeRobot-format data from the Hugging Face hub.

An upcoming PR will add examples and benchmarks.
