Add Curtain left and right commands (same as calibration)

[Jon889]

It would be great to be able to move the curtain bot left and right (outside of the calibrated area) just as the buttons in the app do during calibration. I'd put a PR myself for this but I'm not sure what the command data would be?

Found the commands so will put a PR up sometime

Can you list the commands here? I am interested in using this feature as well. Thanks!

No LEFT and RIGHT commands.
Left and right are based on calibration.

What do you do if the robot isn't calibrated yet?
