Adds Android phone teleoperation as a device

[louislelay]

Description

Inspired by LeRobot’s new phone teleoperation feature of LeRobot, this draft PR adds Android phone teleoperation as a device using the teleop PyPI package

This PR focuses on the Android implementation since I don’t have an iPhone to test on, but given LeRobot’s generalized approach, it should be doable.
