"alicia_d_leader" is missing from teleop.type, and "teleop.directly_controls_robot" support is missing from lerobot-teleoperate

1. "alicia_d_leader" is missing from teleop.type

When using lerobot-teleoperate with Alicia-D Leader and Alicia-M Followe pair. User will see "alicia_d_leader" is a invalid choice. The cause is "alicia_d_leader" is missing from teleop.type in src/lerobot/scripts/lerobot_teleoperate.py. I add it back and created this PR.

Reproduce command and error message:

#2. "teleop.directly_controls_robot" support is missing from lerobot-teleoperate
When use lerobot-teleoperate without "--teleop.directly_controls_robot" flag or with "teleop.directly_controls_robot=true". The teleoperator controls the robot through the direct hardware connection, sending the action again from the computer would duplicate the command, but lerobot-teleoperate isn't implemented to skip the transmission to respect the flag. The commit add the implementation to lerobot-teleoperate.py
